* More or less completed the network notification module - it does not remove

old invalid user listeners yet, though (ie. if a team dies).
* Implemented userland network monitor functions.
* Added a few notifications to the network stack, even though this part isn't
  complete yet (especially notify_interface_changed()).
* Added optional debug output to the notifications module.
* Added the module to the image, it basically works now (tested).
