Add option to dump logs/errors to a file

[aragilar]

Is your feature request related to a problem? Please describe. Currently there is a small panel which displays errors. If there's a number of errors (e.g. issues with the network), this changes rapidly, and there is no way to see what previous errors were, or if they were cut off.

Describe the solution you'd like A CLI option to write all errors (and maybe warnings) to a file.
