[WIP] Removed translation strings made extraneous by 6c78fd1a641bd8e15645f42a9...

I noticed the translation files still had translations for strings removed in 6c78fd1a641bd8e15645f42a97512a0a128377e1 so I deleted them. 

I'm not entirely clear on how these PO files work--they appeared to contain line numbers in the comment right above each strong, not sure if these are automatically generated or not, so if I messed something up, just let me know and I'll fix.
