8ff5e2c283 - fixed/re-implemented media search
- fixed search tipps (topwords, now appearing at the bottom of the page)
- added search consequences execution (deletion of bad referenced some time after the search happened)
- added some formatting at network table

daf0f74361 joined anomic.net.URL, plasmaURL and url hash computation:
search profiling showed, that a major amount of time is wasted by computing url hashes. The computation does an intranet-check, which needs a DNS lookup. This caused that each urlhash computation needed 100-200 milliseconds, which caused remote searches to delay at least 1 second more that necessary. The solution to this problem is to attach a URL hash to the URL data structure, because that means that the url hash value can be filled after retrieval of the URL from the database. The redesign of the url/urlhash management caused a major redesign of many parts of the software. Since some parts had been decided to be given up they had been removed during this change to avoid unnecessary maintenance of unused code.

4779f314fe first version of next-generation search interface:
- snippets are not fetched by browser using ajax, they are now fetched internally
- YaCy-internat threads control existence of snippets and sort out bad results
- search results are prepared using SSI includes
- the search result page is visible right after the search request, the results drop in when they are detected
- no more time-out strategy during search processes, results are shifted within queues when they arrive from remote peers
- added result page switching! after the first 10 results, the next page can be retrieved
- number of remote results is updated online on the result page as they drop in
- removed old snippet servelet (which had been also a security leak btw)
- media search is broken now, will be redesigned and fixed in another step

e332b844b2 - enhanced remote search: during waiting time for remote crawls
some urls are fetched so the url cache can be filled with these urls
- the url-prefetch is used to sort out some unresolved urls
- the snippet-fetcher is triggered with the search event id. This is used
  to remove missing snippets from the search cache so they will not be displayed again

a34d9b8609 * added a search history cache that maintains search results for 10 minutes
it is necessary for the new search process that will do automatic re-searches
a positive effect is, that when a re-search is done it can be monitored how many
results had been contributed from other peers. The message for this contribution
was moved from the end of the result page to the top.
* enhanced re-search time when a global search was done an the local index has
already a great number of results for this word
* re-organised presearch computation; must be further enhanced

- re-designed local result accumulation, will be further enhanced with snippet fetcher

f8de19fb2f robinson cluster: added client-side protocol implementation
- the network configuration page shows a new option: robinson clusters
- when a global search is made, all robinson peers are excluded, but:
- robinson peers/clusters that provide peer tags and where search words match
  such tags, they are included in global search. Therefore, robinson peers/clusters
  support the global yacy network with their indexes, without doin DHT-exchange

2f3b518169 temporary patch for startup-problem:
http://www.yacy-forum.de/viewtopic.php?t=3854
This is a serious problem that is caused by the database bug between 0.511 - 0.513
which produced a large number of double-entries in the RWI index. The uniq()-method
tries to fix this, and it does not terminate when the index is large and the number
of double-occurrences is also large. This patch does simply implement a time-controlled
termination, which does not heal the inconsistency problem. The uniq-method itself
is correct and does not need a bugfix, the non-termination is simply caused by the large number
of data that is shifted during the process. It was possible to reproduce this behaviour
in a test environment.
A real fix would need to:
- enhance the uniq()-method by using a recursive, binary segmentation of the array to be fixed
- uniq() must report the entries that are double
- the double-entries must be deleted from the collection index (from the index and the collections) to heal the problem

861f41e67e redesigned NURL-handling:
- the general NURL-index for all crawl stack types was splitted into separate indexes for these stacks
- the new NURL-index is managed by the crawl balancer
- the crawl balancer does not need an internal index any more, it is replaced by the NURL-index
- the NURL.Entry was generalized and is now a new class plasmaCrawlEntry
- the new class plasmaCrawlEntry replaces also the preNURL.Entry class, and will also replace the switchboardEntry class in the future
- the new class plasmaCrawlEntry is more accurate for date entries (holds milliseconds) and can contain larger 'name' entries (anchor tag names)
- the EURL object was replaced by a new ZURL object, which is a container for the plasmaCrawlEntry and some tracking information
- the EURL index is now filled with ZURL objects
- a new index delegatedURL holds ZURL objects about plasmaCrawlEntry obects to track which url is handed over to other peers
- redesigned handling of plasmaCrawlEntry - handover, because there is no need any more to convert one entry object into another
- found and fixed numerous bugs in the context of crawl state handling
- fixed a serious bug in kelondroCache which caused that entries could not be removed
- fixed some bugs in online interface and adopted monitor output to new entry objects
- adopted yacy protocol to handle new delegatedURL entries
all old crawl queues will disappear after this update!

30888e7a2f implementation of search constraints

This is implemented by scraping information for constraints from a web
page during parsing, and storing flags to the pages within the web index.

In this first step, only information for index pages ("index of", directory listings)
are scraped and stored in flags
- added new flag class kelondroBitfield
- added scraper method in condenser
- added bitfield structure for all scrape types (see also condenser)
- added bitfield structure for appearance locations (see RWIEntry)
- added handover protocol for remote search and index distribution
- extended kelondroColumn class to hold bitfield types
- added another search attribute on search page (index.html)
- extended search-filter to enable filtering of non-matching constraints
- set all new database types to be default
- refactoring: moved word hash generation to condenser class

a5dd0d41af - refactoring of plasmaCrawlLURL.Entry to prepare new Entry format
- added test migration method to migrate the old LURL to a new LURL
the new LURL will be splitted into different tables for each month
this solves several problems:
- the biggest table in YaCy is splitted in different parts and can
  also be managed in filesystems that are limited to 2GB
- the oldest entries can easily be identified, used for re-crawl und
  deleted
- The complete database can be limited to a specific size (as wanted many times)
