I've decided to get rid of the GDI+ PNG handling. It doesn't improve anything performance-wise, adds coding overhead, and probably isn't any faster than libpng. GDI+ also doesn't support APNG. This version does. NOTE: If I add APNG export, I'll need to use the included libpng in Ubuntu builds, since Ubuntu still has libpng-1.2, and it's a version that doesn't support APNG. Reworked the bundled library system to be similar to the one in mcrecover, but improved. Added "-fpic -fPIC" to all extlib static libraries when building for Linux systems. This is needed for libpng, but might not be needed for other libraries; nevertheless, it should be set. TODO: Use libpng in the Windows build. It's being linked in, but it isn't actually being used for anything yet.
