Currently Fawkes always run in the foreground. To allow for safe running over a remote SSH connection screen has to be used. Suspicion was in Suzhou that there have been screen-related problems on the Nao that caused some trouble as soon as the network cable was unplugged.

To make it easier to automatically start Fawkes when the robot boots up and to allow for easier running without screen the Fawkes main application should support a daemonized mode. In this mode Fawkes should automatically start into the background.

The idea is to use libdaemon to implement these features. libdaemon is already a requirement for Avahi and thus should be available on all target platforms anyway. It also saves code that is necessary for successful forking/daemonizing. The daemonize support should be made optional such that libdaemon is an optional requirement.

I'm going to work on this now now, as this should be an easy one to get started again after Suzhou 2008...
