TSAGE: Fix for Quinn's visage in R2R forest campfire sequence
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.
