Fixing issue with case sensitivity in Mac OSX

Discussion here:  https://groups.google.com/forum/#!topic/eclim-user/-JN0CaFzUsE

This is every place in eclim where there was a case sensitivity flag added to a regular expression that was guarded by a "has('win32') || has('win64')" if statement.  I made these changes in my eclim installation and it now successfully picks up the correct project.

This was forked off the 2.3.4 tag, which is the version that I am using.
