Merged Qt, SDL and WRL frontend on the same corewrapper
Moved OpenGL code out of SDL and Qt frontends to OpenGl backend
(JGfx.cpp)
Updated file system and network code to be compatible with WRL
- added 2 menus to wait for connection and wait for deck selection
- tested compilation on Qt Linux, Qt Windows and PSP
- deactivated everywhere (NETWORK_SUPPORT to activate).
- JGE updates : main accepts argv/argc. Compilation variables for MP3 and Network support
- Minor fix in Wagic (potentially fixes crashes when using activated abilities several times in onr turn. Couldn't reproduce the issue)
