Initial import to CVS. Basic functions are working, albeit with a couple of showstopper memory bugs and many missing features. Detaching, reattaching, creating new sessions, listing sessions work acceptably for using with shells. Simple curses programs (top, systat, tetris) and more complicated ones (mutt, emacs) that don't require scrolling regions (ESC[r) mostly work fine (including mutt, emacs). No status bar yet and no key remapping or other customisation.
