Yet more progress on Subsurface-mobile

[Dirk Hohndel]

New Android binaries are on daily and should soon make it through the Google Play store.

These are based on the latest master (-558) which includes a sync with the latest plasma mobile components (thanks Sebastian), a fix for the slow scrolling that Linus pointed out (again, thanks Sebastian), and a bunch more code from me to continue the add dive / edit dive features (you can now edit pretty much everything including dive date and time), various bug fixes and imperial units for people in the US.

As always, feedback is extremely welcome.
