Changeset 3339 for code/branches/resource/src/orxonox

Timestamp:

Message:

Moved GUIManager::getLevelList to LevelManager because the GUIManager has nothing to do with levels.
I also had to change the way the information flows: Instead of operation on the Lua state, you tell the LevelManager to compile the list and then get the elements one by one.
The reason for this change is simple: There is no way to know from which LuaState the call came (without making an ugly hack in Tolua itself).
