Hemiptera Bugtracker at bugs.linux-forks.de

A simple interface for mail between RL and ingame mail should be created for e.g. #23.

Users are assigned with an email address such as <username>@player.linux-forks.de where the data between the email and ingame mail are the same.

For security reasons, a setting can be made to allow only sending to / receiving from certain domains (e.g. *@*.linux-forks.de)
