WINTERMUTE: Add quite a bit of hackery to allow Reversion 1.3 to select languages properly.

Reversion 1.3 seems to have one language file in it’s main-folder, and
a full set in languages/ (not language/ like a few other games), the names
of the language-files are also different from what we’ve seen earlier.
