add autoindent (-a) and chording.
clean up argument parsing.

sam -r machine filelist... from presotto
Add the #goo to allow use in C++.
Silence a few more warnings. Strip down the mkfiles more. Fix bug in X11 mouse handling, note groups.
Changes for Mac OS X. Most important is stack sizes in samterm,
