Anti-Snooze Alarm Clock

Based on feedback from users, I've added a couple of new features to the firmware.

First off, you can now set exactly which days of the week an alarm corresponds to. (The old system only gave three options: weekends, weekdays, or every day).

Secondly, there is now an options dialogue to switch between 24-hour mode and 12-hour mode.

As a result, the e-paper display's font sizes had to be decreased to squeeze more information in.
