Rewrite png2c.pl in C++. This allows us to always generate icons during build, and in the future remove a Perl dependency.

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.

Replace internal vector font with LibreCAD's GPLv2+ vector font. This font is less complete than our bitmap font, Unifont: Unifont has essentially complete Unicode coverage and LibreCAD's font only has Latin, Cyrillic and Japanese, but it can be extended rather easily, so this should be fine for now. These embedded fonts fatten glhelper.o quite a bit: bitmapfont.table.h is about 8M in gzip-compressed bitmaps and vectorfont.table.h is about 2M in raw vector data. In spite of that it takes just around five seconds to build glhelper.c on my laptop, so it should be fine. The final executable grows from about 2M to about 8M, but this is a small price to pay for fairly extensive i18n support. The new font has somewhat different metrics, so the rendering code has been fudged to make it look good.
