Fix up Turkish localization

The Turkish localization data was ... obviously done by a cyborg using machine translation. Once #22 is merged, this PR should be 3 commits with proper translation of  terms. I'm not sure what your criteria are for enabling a language by default in the interface, but assuming it is just a matter of having had them reviewed, 61c7865 should take care of that. I had some trouble with the book names system so I left the array in fc5b37d commented out, but those are proper book names for when the book name localization does work.
