538e375901 replaced old caching method for computed word hashes with a better method. The word hash computation is a new performance bottleneck (after the IO bottleneck was removed with the IndexCell data structure) and a better caching for word hashes was necessary.

c8624903c6 full redesign of index access data model:
terms (words) are not any more retrieved by their word hash string, but by a byte[] containing the word hash.
this has strong advantages when RWIs are sorted in the ReferenceContainer Cache and compared with the sun.java TreeMap method, which needed getBytes() and new String() transformations before.
Many thousands of such conversions are now omitted every second, which increases the indexing speed by a factor of two.

c2359f20dd refactoring: better abstraction of reference and metadata prototypes.
This is a preparation to introduce other index tables as used now only for reverse text indexes. Next application of the reverse index is a citation index.
Moved to version 0.74
