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.
WINTERMUTE: Add a fake detection entry for Czech Dead City.

The language data for the Czech version are in data.dcp, but the pairs
of {language.dcp, data.dcp} get preference over just a match on data.dcp,
thus we need to detect Czech as one of these pairs, giving the user the
choice of language on detection. In this case I just copied the english-detection.
AVALANCHE: Repair the timer.
FULLPIPE: Started scene02 implementation
TSAGE: Don't assert in PlayStream::getFileOffset() when no data exists

This function returns 0 when no valid voice data is found, at the place
where it's used. This prevents the game asserting during the intro, when
no speech file is present, in platforms with limited disk space
