this should reduce IO a lot, because write caches are now actived for all databases
- added new caching class that combines a read- and write-cache.
- removed old read and write cache classes
- removed superfluous RAM index (can be replaced by kelonodroRowSet)
- addoped all current classes that used the old caching methods
- more asserts, more bugfixes

- generalized object caching and added new object caching class
- added object caching wherever kelondroTree was used
- added object caching also to usage of kelondroFlex
- added object buffering (a write cache) to NURLs
- added many assert statements; fixed bugs here and there
- added missing close methods to latest added classes
