* Added DraciEngine::_initArchive and made Game use it. Fixes a memory bug because Game uses pointers from the init archive which should outlive it (but didn't previously).

* Added support for setting loop status to Game.
* Made some GPL commands check whether we are in the correct loop status before executing.
