Remove Digest and Fuzzy match warnings

Upgraded the fog and gibberish gems to suppress the "Digest::Digest is deprecated" messages when you run a rails/rake command, and also suppressed the FastGettext fuzzy match warnings to have cleaner output when running commands. I wasn't totally sure what those fuzzy match warnings were, I think it has to do with the translation of strings, which I'm guessing we could focus more carefully on later on.
