6eaa5a0e64 enhanced local search speed. The ranking process is now 6 times faster that before.

5c1b444690 some redesign of min/max and normalization computation during search result ordering
this saves about 1 millisecond for each URL reference, which has some good effect
on the search result computation if a word is searched that appears very often
(speed-up of 1 second and more)

2cb16824e3 removed support for old database structures.
The new collection index will be more generalized to support other indexes
i.e. YBR block-rank computation. A clean-up of the many conditions to support
the old database was necessary.

0a050bc043 enhanced ranking
- redesign of data storage in plasmaSearchRankingProfile
- profiles are extended by new ranking parameters
- new RWI ranking parameters are considered during ranking
- appearance attributes (i.e. emphasised text) is now considered
- faster ranking
- some attributes that had been checked during post-ranking can now be
  checked during pre-ranking phase
- removed old ranking parameter on index.html page (will be replaced by profiles in the future)
- ranking can now consider appearances of media content
- snippet-loading for media types now work correctly (fetches only from the wanted media)
- ranking-profiles can be handed over the remote peers and apply there also
- re-search of same query with different domain now also re-triggers remote search

30888e7a2f implementation of search constraints
Such constraints may formulate specific restrictions to web searches
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
