[Watch face] Date Countdown

Because I needed to allow custom settings, this is actually an app with a watch face for the root window. You can access the settings by click the select button, at which point you can change the event date and also choose from a small list of event titles (or leave it blank).

Known issues include the inability to save settings across sessions, no support for DST in countdown length calculations, and the menu lacking click-and-hold functionality.

It's my first Pebble project, so please, let me know if there's anything you see that I can improve upon or need to fix. Or just fork it :)
