More rFile cleanups and fixes.

Was using fileExists/dirExists before when really should have just been exists. File or Dir doesn't matter and would only create false negatives.
Current working directory shouldn't really be used at all. This is just the folder the application is run from (not even where the .exe resides).
Some of the infos required by vfsLocalDir such as executable may not be portable. Not sure of their intended function as they are never used.
