Turkish localization for TotalSpaces

Finished the translation to Turkish.

However, I could only see the changes in the drop-down menu and the preferences icon labels. The text in the preferences dialog itself did not change. I could not run `rake validate` since I couldn't see a rakefile, but I believe the file is valid.
