Ben Gruver 1e655c2e54 Handle unicode filename collisions on mac
Some unicode characters are considered equivalent for filename purposes on mac.
This adds logic to treat these collisions the same way as case sensitivy
collisions are currently handled -- by adding a numeric suffix to the
file/directory anytime there is a collision.

See pull request #789 for more information.
