[Omake] SVN Commit: OMake Build System [0.9.8.x] (Rev. 10648)

[Jason J. Hickey]

Implemented the strictly case-sensitive Omake_cache.stat, and use only case-sensitive
comparisons on nodes.  This should be considered a proposal, to be reviewed.

Potential problems:
   - People might wonder why OMake is case-sensitive on Win32/MacOS etc.

Cleanup, if we decide to go this way:
   - Nodes use only the fine comparison, so the code can be substantially
     cleaned up.
   - The case-detection code should be moved to Omake_cache.
