New "FMU" behaviour specification
Users should now be able to add an “FMU” beahvior specification.
This requires:
- defining a new model element “FMUSpecification” which should inherit from IComponentBehaviorDefinitionSpecification (->in the cosimulation plugin, in the cosimulation.ecore file)
- ensure it can be added to a component by drag and drop
- ensure it is not possible to add a state automaton to a component if it already has an FMU specification
- define an editor for this new specification: this should be opened by double-clicking a component containing an FMU specification and should contain just one field allowing to provide a path to the FMU file
