Subsurface 4.8.5 and Subsurface-mobile 2.1.6 soon

[Dirk Hohndel]

As I mentioned, I want to get two quick updates out for all the platforms.
You can look at what I am thinking of shipping at the v4.8-branch. It's
possible that I skipped your favorite fix - my apologies. I'm planning to
do a 4.8.6 (or maybe 4.9 - new filter widget could be the excuse to rev
that) in a couple of weeks... or more precisely, when we are happy with
the filter widget.

I will push a few more commits in preparation in the next couple of hours.
If I don't stumble across anything too ugly I might publish the release
tonight (New Zealand time), more likely I'll do it at some point tomorrow.

If you find anything horrible, please let me know. I'll try to exercise
all of the build environments that I use for the release builds - these
will have oddly low version numbers - master is at 4.8.4-191, but the v4.8
branch is at 4.8.4-63... we can argue that the way these 'versions' work
makes no sense, but that's besides the point.

If I remember I will follow up to this email with links to the various
binaries that you could test if you wanted... or I'll just release it and
have our users be the testers :-)

What is available right now can be found here:

Certainly the Windows installer and the (unsigned) arm apk (the arm64 has
BLE issues) are worth testing as is. Also of course the AppImage.

I'll upload a Mac DMG, upload a signed apk to downloads/test on our web
server, try to get an iOS build ready and also trigger the distro builds
on Launchpad and OBS... 

Anyway - yell if you find something that I should include before 4.8.5

Thanks
