mobile/statistics: add a statistics page on mobile

This adds a reasonably flexibile mobile page that tries to do the right
thing for both portrait and landscape mode. In order to get the most out
of a mobile screen, it's implemented in a way that always gives it the
full screen (it does so by emptying out the page stack and being the
only page shown - brutal, but effective).

This commit also contains a bunch of other random cleanups that didn't
really justify being in separate commits.

Parts of this was written by Berthold, hence the double SOB.
