6388a58fc7 better memory management and slightly less (in total and temporary) RAM allocation:
- confirm that database objects that are not supposed to grow do not have a index memory management that is designed for growth
- changed index sorting method in such a way that it allocates less objects during quicksort
- database classes classes renaming (shorter, naming addresses that objects hold in RAM)
- added a large number of asserts to check if objects actually take the RAM that they should have

56ff9d5fd4 - extended news size from 512 to 1024 characters
- a new news db will be created (news1024.db), the old one (news.db) can be deleted
- peers with too large news payload are not ignored any more (they may have been invisible because they had a too large news payload!)

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.

9a674d8047 - After the removal of the Tree class some code simplifications are possible. This affects mostly the Records class, which can be refactored and the result of the refactoring results in a reduced number of classes.
- The EcoTable was renamed to Table.

13c666adef performance hack to ObjectIndex put() method:
Java standard classes provide a Map Interface, that has a put() method that returns the object that was replaced by the object that was the argument of the put call. The kelondro ObjectIndex defined a put method in the same way, that means it also returned the previous value of the Entry object before the put call. However, this value was not used by the calling code in the most cases. Omitting a return of the previous value would cause some performance benefit. This change implements a put method that does not return the previous value to reflect the common use. Omitting the return of previous values will cause some benefit in performance. The functionality to get the previous value is still maintained, and provided with a new 'replace' method.

8444357291 added new row interator in kelondro tables files that enumerates rows
without an order by the primary key. The result is a very fast enumeration of the Eco table data structure. Other table data types are not affected.
The new enumerator is used for the url export function that can be accessed from the online interface (Index Administration -> URL References -> Export). This export should now be much faster, if all url database files are from type Eco
The new enumeration is also used at other functions in YaCy, i.e. the initialization of the crawl balancer and the initialization of YaCy News.

dc26d6262b - removed write buffer from kelondroCache (was never used because buggy; will now be replaced by new EcoBuffer)
- added new data structure 'eco' for an index file that should use only 50% of write-IO compared to kelondroFlex
The new eco index is not used yet, but already successfully tested with the collectionIndex
The main purpose is to replace the kelondroFlex at every point when enough RAM is available.
Othervise, the kelondroFlex stays as option in case of low memory (which then can even use a file-index)
