* src/net/messagin.cpp, src/net/messageout.cpp, src/net/network.cpp:
removed replaced MACOSX defines with big endian defines
* src/graphics.cpp, src/graphics.h: added screenshot method
* src/game.cpp: added code, so that when one presses 'alt-p' (for
picture), it takes a screenshot and saves it to a png
* src/Makefile.am, config.ac: added png library stuff
