My first stab at adding features to the GUI: Added shortcut keys for the
Inv, Neg, etc. buttons on the RAM tab. Also added Undo and Revert buttons to the RAM tab. Undo undoes your last change only (and does not undo an undo). Revert reverts RAM to the state it was in when the user entered the RAM tab. These buttons are disabled when they're not useful. git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@605 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
