Quick clean up token adapter
Got zoom to work

* Removed petrinet.zoomTo action and just called to repaint
Fix zooming properly

* ZoomController only needed in petrinet tab
  the paintComponent method applies a scaling matrix with the zoom
  factor in order for all other paints to appear larger
* Components no longer know about zoom
* Only Connectables have a name label now
PetriNetTab observes ZoomController
Remove debug code
Update zoom box on zooming in
Grid is no longer static
Change removeing label from parent to be tab
Fix errors that occured rebasing
Fix arc dragging/selecting issues
