Modified RouteManager to support navigation by "Signposts". This
algorithm should fix alot of bugs. This should also increase usability
of the application.

Buildings dont know about those signposts. Only they know which
building(s) they are pointing to. 1 Signpost is required to run the
simulation, but this is not implemented yet.
Signpost can now be dragged on the field
