Future Pil:
	- Icon
	- Welcome dialog
	- Fix detection of backspace key in the preference dialog. Someone says somewhere:
		"As far as I know, there is no enum or list of key codes. However, to get similar behavior, you can call interpretKeyEvents: in keyDown: which will call appropriate action methods, all of which are documented in NSResponder (e.g. moveLeft:, insertTab:, etc.)"
	- Fix? alert sheets (see NSAlert’s -setShowsSuppressionButton: and -setAccessoryView: methods)

Deadline 5pm:
