564374d1fe - included YMarks in addition to old bookmarks in yacysearchitem.html; don't get confused by the old bookmark dialog, the ymark is automatically added silently beforehand. 
- reworked bookmark creation on crawlstart
- many smaller adjustments to ymarks

85a5487d6d YaCy can now use the solr index to compute text snippets. This makes search result preparation MUCH faster because no document fetching and parsing is necessary any more.

0819e1d397 protection against OOM cases in image parser. See also bugs.yacy.net/view.php?id=54

49e5ca579f added new configuration property "crawler.embedLinksAsDocuments". If this is switched on (this is default now), the all embedded image, audio and video links from all parsed documents are added to the search index as individual document. This will increase the search index size dramatically but will also enable us to create a much faster image, audio and video search. If the flag is switched on, the index entries are also stored to a solr index, if this is also enabled.

610b01e1c3 - added a 'add every media object linked in a html document as a new document' to the html parser. This causes that all image, app, video or audio file that is linked in a html file is added as document. In fact that means that parsing a single html document may cause that a number of documents is inserted into the search index. 
- some refactoring for mime type discovery

0c1b29f3c9 - applied many small performance hacks 
- added a memory limitation in the zip parser and the pdf parser
- added a search throttling: if there are too many search queries are still to be computed, then new requests are not accepted for some time. if after a one second still no space is there to perform another search, the search terminates with no results. this case should only happen in case of DoS-like situations and in case of strong load on a peer like if it is integrated in metager.
- added a search cache deletion process that removes search requests in case that throttling happens

4bea3f9714 hack to reduce resource contention caused by massive UTF8 decodings which use java.nio resources: 
used a ASCII String <-> byte[] conversion wherever possible. Many Strings in YaCy are hashes which are pure ASCII (base64 hashes).
The new ASCII String <-> byte[] conversion method have less computation overhead than the UTF8 conversion.

- added a new storage class for this new cache: KeyList. The domain key list is stored in DATA/WORK/globalhosts.list
- added concurrent solr updates and chunked transfers (50 documents until a commit is done) for high-speed feeding (> 40000 ppm)
- fixed a bug in content scraper that chopped off large parts of crawl lists (using crawl start from file)
