Fix OS X file associations to work on Yosemite
Fix OS X file associations to work on Yosemite

Poedit used legacy way of specifying supported ways. This still works on
Yosemite in the important ways (such as launching Poedit), but Finder
stopped showing file type description and replaced it with "Poedit
Document".

Don't use deprecated (since OS X 10.5) Info.plist keys. Declare proper
UTIs instead.
