Add About section

[airon90]

If you open the app, there isn't any About section, where to show information like link to Github and Weblate, version of the app, license, acknowledgement, ... If you want to report something you have to open F-Droid to find the link to Github or you have to search for it

I agree with you, however this is duplicate of #24 ;-)

I added your considerations there
