Add log file and provide easy way that users can share it with devs/support

[HenrikJannsen]

Currently the mobile logs are not persisted, thus making bug reports very difficult.
We only have the logs from the bisq lib. We should write the logs to file as well and provide in the UI a tool to zip them and share with devs/support.

We also should reduce the size and and number of logs of the bisq core lib. I think its currently 20 files with 10MB which is too much for mobile. I think there is API for adjusting that, I can look into it, otherwise we can easily add that to Bisq 2.

we have a UI in place when an uncaugh exception occurs preseent the user with a summary and a button that takes them to report in our github

allowing to generate a zip of the logs to upload when doing the report would be ideal

I added support to config the log settings with latest bisq 2 branch and my PR branch.

We should still add log beside the error popup, as when users report issues we need logs to investigate.
