-Multithreaded IDManager.getNewID() *use implementation with free IDs stack (instead of classic pool) -support for multiple UpdatePasses. Passes are added by name, and must be called between begin() end() functions. -removed mutex from addEntity() -commit() function added. Used to commit all changes made while update() call. Called automatically by begin() end() functions.
