Needs lots of work. Need context menus in more places. Need better error
checking.

Make Actions menu be View menu.

Something funky is going on with the difference graph, if I add the wrong
button then delete the wrong button, the difference graph still shows
the old differences.

Make button editor have a 3 col version that lets me view and compare
multiple buttons.

The clear log button in the log window should be made to work.

The log window should probably also get a save to file button.
