Items can be given from dialogue scripts, & all npc + trigger loading
automated.

Commands work like this; "/give pistol" etc

The game now loads npc's etc more efficiently. FPS and lag has been
greatly improved,especially after changing the levels[] array. There was
also a bug where the bg was loaded 4 times, which is fixed.

There are some debug printlns lying around, as well as obsolete code,
I'll do a cleanup soon.
