Error and crash reporting functionality (logging)

[krestenlaust]

Is your feature request related to a problem? Please describe.

• With Sentry removed (because of ideological differences I presume), there's a new need for users to report errors to maintainers.

• When I happen upon an error or something that's hard to reproduce on other devices, having a stack-trace or similar to report should prove useful.

Describe the solution you'd like

• A button in settings that can output the latest logs, not sure how it would determine, maybe even open up an issue with the log attached (not sure if that's even possible)
• Some way to access the logs as a user, be it some kind of developer options enabled in the app, or enabling logging files or so.

Describe alternatives you've considered
Find an alternative to friendly, that is opt-in.
