Initial implementation of the new signals and slots class. Fixed command parsing which compared a pointer to a character. Buffer overflow fix in routines which used the limits from the entity tasks. Switched from Sqrat::Object to Sqrat::LightObj in most places to avoid the overhead of the VM pointer. Various other adjustments and improvements. The plugin is currently in a broken state and crashes at shutdown. The bug is unknown at this point.
