This one picked up a lot of inconsistancy so the changes here are pretty
big.

This is getting us much closer to the final UI concept. We have a
quick ring from which we can select typical apps such as clock and
stopwatch which will (eventually) be supplemented with step counting
and heart rate monitoriing. More exotic apps (currenrtly torch, self
test, settings) are all relagated to the launcher ring.

From here we can also bring colour to the launcher!

It is not really the launcher itself that is immature. Rather that the
framework and UI concepts to move between applications isn't complete
yet.
