[Omake] SVN Commit: OMake Build System (Rev. 10927)

[Aleksey Nogin]

FS case sensitivity improvements:
- If the name does not ocontain any upper case characters, abortt the case
  sensitivity early (as we do not really care).
- Test with Unix.access before trying to create test entries.
- Test for all the 3 pairs of ranges that Char.uppercase/Char.lowercase
  recognizes (not just a single 'A'..'Z'/'a'..'z').
