Improve french locale

Fix typo in en locale
Added missing lines on some languages (these should be translated)
A few charset fixes for most languages, as the charset detector isn't very reliable (romanian still a work in progress)
Merge branch 'master' of https://github.com/popcorn-time/popcorn-app
The romanian subtitles bug was a typo (ISO-8859-2, not -9)
