Subject: Expanded demo functionality (preparing for 2.0.0, see #54).
Mostly back to the previous version with enable/disable checkboxes &
one settable and one hard-coded shortcut. I have tried to come up with
a nicer pattern to watch the enabled/disabled checkboxes, but without
external dependencies like Facebook’s KVOController I didn’t come up
with anything better than plain old KVO.
