Update to 0.53

Adds many great things.
- deviceList, for browsers that support it, to REALLY show what the
app'll look like on a tiny screen.
- phonegap and droid detection. isDroid() needs to be replaced.
- sound support!
- using container instead of body to deal with some overflow issues
- and a little bit of goodness to compensate for iOS7 and Cordova 3's
inability to be nice to each other.
