Added Mersenne Twister pseudo-random number generator ( really usefull and fast for some type of games if you want a deterministic random number generator ).

Reimplemented the tResourceManager, now uses std::list instead of std::map, and added some new methods.
cShapeGroupManager and cShapeGroup now inherits from tResourceManager.
Rolled back eeUint and eeInt, now are fine again ( it was changed for testing ).
