Add a visualization of whether the net satisfies the precondition

[mgieseking]

Add a tick-button to the bottom of the editor which is gray when the current net is not in a checked state and green when it is checked correctly and red otherwise.

In AdamModelChecker and AdamSynthesizer there is a method "createPreconditionChecker" which can serve for checking the net. A Petri net with transits and a Petri game with transits have a listener which notifies if s.th. structurally change in the net (see for example the implementation in "PreconditionChecker").

You can create your own listener to gray out and reactivate the button. When clicked, you can use the check method of the "PreconditionChecker" to decide whether the button is green or red. Then deactivate the button.

@mgieseking I assign it to you while you check if its feasible to interrupt this calculation. :)

For getting notified if any changes in the net occur you only have to write a listener implementing IGraphListener<PetriNet, Flow, Node>, i.e., only implementing

 @Override
    public boolean changeOccurred(IGraph<PetriNet, Flow, Node> graph) {

which is triggered when the net has changed.

This listener has to be added to the Petri net with net.addListener(listener).

@annyanich it is feasible and I opened an issue for that #83

I think this was the thing we already missed for the last deadline ;).

Recap of what I said in chat: I will probably not get around to implementing this for the deadline, so as of ab0d54bfe6320d9b92caae76f59124e7657a7f1d, the checking simply happens before each and every type of job from the solve/analyze menus. In the log window, you can see a message in the server before and after the checking takes place.

I will put this as 3-priority for now
