Rewrite ttf2c to use GNU Unifont and merge with pngchar2c.pl.
After this change, SolveSpace does not contain nonfree assets. Additionally, Perl is not required for the build. Note that in the US, case law suggests that copyright does not apply to bitmap fonts: http://www.renpy.org/wiki/renpy/misc/Bitmap_Fonts_and_Copyright Nevertheless, it was prudent to replace the asset with something that is unambiguously free.pull/4/head
