pandora port with separate platform initialization files and global functions enhanced

was working a bit more on the pandora port and moved the main #ifdef's into separate platform files (added platform.h and platform.c) - can't test if it still works on the n9xx platforms as i dont have one of these.

most of the modifications within apklib and jnilib have been done to get unity based games working. though the module still doesnt work (SEGFAULT on nativeFile)

fixed angry birds module for the pandora

enhanced the cut the rope module to get to the start screen. added a preliminary png loader for that, too.

as i'm mostly working with codeblocks the makefile probably needs some update, too, which i haven't done yet.
