[kepler-dev] ui: context menu in actors palette

[Tobin Fricke]

It would be handy if right-clicking on an actor in the actor palette would
yield the same context menu as right-clicking an actor in a model.  It
would make exploring the actors library a bit more expedient (as you would
be able to access 'Look Inside' and 'Get Documentation' without having to
first drag a temporary instance of the actor into your model).
