Subject: [PATCH] * improved quake2 support by added a quake2 boolean to the
 CGameDescription class - this allows us to even use the quake2 surfaceplugin
 function (like e.g. SetFaceTexdef_Q2) without a hardcoded game name of
 q2.game or heretic2.game * added support for relative md2 skin paths * fixed
 wrong _pico_printf call
