Show server warnings/errors to DM

[Kruptein]

An option to as a DM see the errors and other warnings that occur on the server related to your session could be interesting for those users that don't host PA themselves and have some issue.

This could potentially be integrated in some future chat/message aspect of the client.

• Some messaging system is needed, would also be nice to have a chat and also a roll log (channels and stuff)
• Should be possible to enable server logging channels to be sent to this messaging system.
• Use permission management to allow some roles to read these channels.
