 cache
- didn't cache anything since ages (gb_cache_entry.clock was always zero, i.e. always out-of-date). Was already broken in [2].
- increased max. cache memory from 25Mb to 50Mb
- increased max. cache entries from 8192 to 16384
- destroy cache on GB_close (fixes biggest and most useless ARBDB memleak)
- changed cache indices to uint16_t (reducing each cache entry by 8 byte (16 byte;64bit)).
- rewrote complete cache code removing much duplicated code
- added debug code to calc cache stats
- increased max. undo memory from 10Mb to 20Mb
