Updates libfreetype to i386 and includes libpng

- Includes libpng a new dependency into gameplay-encoder
- Reverts libfreetype to i386 ONLY version (intention was to make gameplay-encoder i386/x64 however other issues prevented that for occuring for this release) Will re-check in 64 bit version once those obstacles have been overcome
