Title: GRAPHICS: Reimplement the PNG-decoder using libpng

This implements the PNG-decoding using libpng.

Currently, it simply returns false on decode if libpng wasn't linked in, which makes for a crash in Sword25.

As far as I know, it should work fine. (I did test it with both the problematic WME-games AND Sword25)
