01e0669264 re-designed some parts of DHT position calculation (effect is the same as before)
and replaced old fist hash computation by new method that tries to find a gap in the current dht
to do this, it is necessary that the network bootstraping is done before the own hash is computed
this made further redesigns in peer initialization order necessary

af25c98306 enhanced local search performance in case of a remote search:
there is no waiting until the local search terminates to show the result page.
the local search appear like all other results from remote peers using a separated thread.
This has especially a stron effect, if the local index for a specific word is large.

842308ea97 - redesigned crawl start menu, integrated monitoring pages
- removed web structure picture from indexing menu and grouped it together with htcache monitor
- added a database for terminated crawls, when a crawl is finished it is automatically moved to the new database
- extended crawl profile edit servlet, shows now also terminated crawls
- option that was used to delete profiles is now redesigned to a function that moves the current crawl to the terminated crawls and removes all urls from the current queues!
- fixed here and there problems with indexing queues
- enhances indexing speed by changing cache flush sizes.
- changed behaviour of crawl result servlet: the list of crawled urls is shown if there is one, othevise the overview window is shown

attention: the new profile databases are not compatible with the old one. current crawls will be lost! the web index is not touched.
next steps: the database of terminated crawls can be used to start with them a new crawl. This is useful if one wants to re-crawl specific pages and wants to use a old crawl profile.

341f7cb327 steps to enhance remote search performance:
- added a file size limitation, that disallows parsing of large documents during (offline-) remote search
- added profiling information to search result computation, visible at search access tracker. this info shows used time for URL fetch and snippet computation

1488769e1f cleanup of unmaintained and outdated performance methods:
removed object pools in httpc. Object pooling is not recommended,
if the creation of the object is not time-intensive. Object pools are only useful,
if there is much computation necessary to create some basic data that is stored
in the object pool and can be re-used. This does not apply to object pools in YaCy.
Object pooling of client sessions would make sense if they would allow re-use of
living connections to other yacy clients. But every connection is closed after usage
of an object in the client pool, therefore the YaCy server client objects are not such
that hold hardware/network-allocated entities.

5b0c1449e1 various fixes and cleanups for blacklist handling:
1. avoid adding duplicate file name entries in config properties for lists, 
2. correctly merge all path masks from all list files for the same host masks,
3. rewrite helper methods standard java methods for Collection transformations,
4. merged various methods with identical functionality for different Collection implementations into one,
5. minor refactoring to improve code readability.

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

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

72752bb503 because of a new database structure handling, the memory need for accessing
collection objects has been reduced to 50%:
- set new memory calculation functions for indexing process
- adjusted guessed memory amount
-> Testing needed:
   try new recommended value (see performanceQueues) and see if OOMs occur.
-> report maximum recommended value, so we can set new default values.

- there is less memory transfer on the bus, especially for collection index
