new beta and new alpha

[Dirk Hohndel]

I promoted the last alpha (-867) to beta to get it more widely tested.
That's the one that should have the near-final UI and has all of the
functionality that I expect to be in the first version of
Subsurface-mobile.

It does have one known stupid bug that I caused - when you edit several
manually added dives, all of their samples (created by fake_dc() calls)
point to the same static set of six samples. Oops.

So there's also a new alpha -870 with an attempt to fix that.

In order to get closer to something we can release, can I ask people to
please test specifically adding dives and editing dives and tracking very
carefully if the edits are tracked in the profiles and if the dive data
that gets saved to the cloud ends up matching what was supposed to be
there?

And, of course, overall, try the menus, try all the options, see if you
can make it break in creative ways.

I want to get back to working on the desktop version, create 4.5.4 with
the newest libdivecomputer (which fixes a couple of known bugs). Work on
completing the dive site management for the desktop version. Etc.

But first, I want to get to the point where we can make the first public
release of Subsurface-mobile.

So please help.
