WINTERMUTE: Add bold-font support for FreeSans.ttf (and only FreeSans for now).

This is mostly a quick fix to solve the rather common case of wanting
to use bold Arial. This will not handle the user adding the actual Arial.ttf
file to the folder yet, but atleast it solves the common case of having
to fallback to FreeSans.

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
