#7 design a real gui

[Brian Fegler]

instead of listing everything as it's own item, i'm
just dumping them all in here. the list is too over
whelming.

results list
down button on last element in list needs to go back to
command line.
fix scroll bars getting in the way during
(!scrollbar)->(scrollbar) transition
realign results list on a repaint

command line
(ctrl|alt)(up|down) for ans and entry
have the command line take the focus on start up and
window change

misc
have a different cursor while computing
have the gui be able to stop the calculator when it is
hung (from doing 9!!!!!!)
readfile:FILE, printtofile:FILE, appendtofile:FILE,
testfile:FILE
warnings can go to three palces: alert_box, STDOUT, logger
