Fixed logging destination
Fixed handling of remote media
Fixes for local and from_broken repair and ReroutingExperiment

Global repair still has issues.
Added handling for new events occuring for layers
Fix for half-closed lower layer connections from global repair
Adaptations to GUI code changes
Initial import of lower layer supporting the recursive interface

The layer does not support the remote access to media objects. It uses
the same command name "create bus" for creating the media objects. Thus,
it can not be used in parallel to the fog.bus plug-in (For debugging
purposes, the fog.bus project has to be closed in an Eclipse workspace
containing both projects).
Added license (dual and EPL)

Same licenses as in the fog.bus and fog.bus.view plug-ins.
Allow not only Exceptions but also Error objects as failure reason
New recursive lower layer (broadcast scope) with simple view
Beautified GUI output
