Configuration options with language selection

I like your watch face, and I was using an English translation.  But it stopped working when I upgraded to the 2.0 firmware, and I could not find a replacement.  So I forked your code to make one.  Along the way I added configuration options, which can be accessed through the Pebble app on the phone.

These properties are now configurable:
- color (white-on-black or black-on-white)
- text alignment (center, left, or right)
- language (English or Swedish)

There is enough room in the binary to add a bunch more translations.  Please forgive me if I mangled the Swedish while modifying the code.

This version is not quite ready to publish - there seems to be a memory leak that is triggered during the handle_minute_tick call.  I will send an update when I track that down.
