Expand the spelling fix of some terms to all languages

[NovaRain]

Based on brussell1's pull request (#125). I also unfuzzy some strings that were already translated but not being actually applied to msg files (mostly in qccurlng.msg, qhprzrch.msg, and nhmyron.msg when I double-checked the consistency of spelling).
