Big, big commit!!

Big, big commit!!

1) Remove WITH_FREETYPE2 from code, so now blender always need freetype2
2) Remove the old bmfont
3) Remove ftfont and bFTGL library
4) Implement a new BLF_draw_default function for place that still need/use
   the old BMF api.

I try to update both, scons and cmake, but I only can test with make, so
hope all work fine.

MSVC is broken, but I don't have Windows, things to search and fix are
any reference to WITH_FREETYPE2, FTGL and BMFONT (take in care that
blenkernel also have a BKE_bmfont.h, this don't have anything to do with bmfont).
        Always have to link/include the freetype2 library
        Remove any reference to libbmfont
        Remove any reference to libftfont
        Remove any reference to libbftgl (or libbFTGL)
