v2.8.0

Nothing fancy: mostly just updates and bugfixes.

in particular:

• support for Android 2 and 3 dropped
• support for Android 11 added
• dependencies and build tools updated
• bugfixes with regards to shortcuts
• a bit of support for autofill
• small changes to the German translation

notes:

• The file ending in gp is the one you can download from Google Play.
• The file ending in gpo is the one I uploaded to Google Play.
• The file ending in fd is the one F-Droid built. You should install this one.
