Added libvterm to makefile (and glib2 which it depends on)
Fixed a bug where the global settings struct wasn't delared as extern in it's header file and added a lisp_tokenize function
Removed lots of old code from the lisp interpreter - it won't be used nearly as much as originally expected
Continued work on the vte - I'm using libvterm after all. It's still buggy though - hopefully it's fixable
