[REQ] Enable client debug logging and log retrieval from server

Sometimes we don’t have easy/direct access to the client and it would be handy to
enable client debug logging from the server. Perhaps a check
box under Settings > Client > Advanced, something like “Enable debug
logging on the client”.

Then maybe have something like a button under the Activities section to retrieve the debug log from the client:

If another button is created in Activities, changing the button labels to “Server log” and “Client log” might be clearer too…
