Added x86 and x64 builds of freetype 2.5.4

I added 32 and 64 bit builds of freetype 2.5.4. There are MSVC 10, 11, and 12 versions.

They are statically linked to Zlib 1.2.8, LibPNG 1.6.16, BZip2 1.0.6 and HarfBuzz 0.9.36.

I also patched fttypes.h to use __int64 instead of long when on Windows. The patch is included in the commit.
