Replace deprecated links

[fm-sys]

Many links inside the app aren't up to date anymore.

Question @maks: do you accept PR's and are you still actively maintaining the fork (do Playstore releases, etc)? If so, I would happily contribute to the repo...

Yes I'm am still maintaining this fork and doing releases on Play. And yes am happy to receive PRs.

And I'm not a native German speaker so my German is quite sketchy, so happy to receive translation updates.

What about setting up GitLocalize for this repository? That would probably make transactions a lot easier... (It's free BTW 😉)

An alternative tool would be Crowdin (free as well for open source):

I already have good experiences with such tools and there are quickly people who gladly help with translations if you add a small link to the tool somewhere not too hidden into the app...
