Template Blender file for animations.
Changed `driver_RunFrame()' to maximize framerate.

This results in a much more pleasing visual than limiting the
framerate.
Altered font code to support multiple font types.

Right now TTF is the only one that's implemented, but soon we'll
add code for our own custom bitmap-based fonts.
Declared `font_NewFontTTF()' in header.
Added a segfault handler and removed a warning.

Now when a segfault occurs we dump a stack trace and attempt to
shut down SDL (so that people's screen res reverts to normal =]).
Also removed the declaration of an unused variable `t' in
`main()'.
