1defd580bc - added option to localization search to distinguish between a search for a location according to the search word only or for the relation between a web search results and locations found in the metadata fields 
- used that to display two layers on map: cities and search result locations
- added many marker grafics for the display of the markers on the map
- some refactoring of the yacy news code plus bugfixes for latest move from Tree to Table data structure

7b69d79727 enhanced remove() operation: in many cases it is not necessary to return the removed object to the called. 
for such cases the delete() operation was introduced which is sometimes much cheaper in operation since it does not need to create objects to hold the removed content and it does not need to read those objects.

64f29f990e a collection of performance hacks and code cleanup: 
- removed usage of URL-Caches which could have been a memory leak
- removed unused classes and methods
- removed not necessary synchronizations
- added synchronization hacks where possible
- fine-tuned crawling speed to prevent IO of balancer
- fixed a bug in IODispatcher that may have caused that no merges were done
- reduced number of parameters in very often called methods (compare methods)
- reduced complexity of data structures of now massively used HandleSet class
- reduction of new String() and getBytes() usage / new methods to support this transition

4a5100789f replaced _all_ size() == 0 with isEmpty() and all size() > 0 with !isEmpty(). The isEmpty() method is much faster in some cases, especially when used to access badly balanced hashtables where an size() operation becomes a large iteration.

4df88a4e7a - fixes for missing or bad hashCode computation 
- fixes for bad equals() methods that had not been used by hash maps and therefore some classes did not work as objects in hash maps.
- this may also affect some cases where double-checks should have been, but did not work.
