ListenHash: remove 'model', 'collection' limitation

[TomAtGithub]

I do not see any reason for limitating the listen hash to model, collection, mediator.
With the optionNames property i can add 'native' additional models or collections to a view.
So i think it would be consistent to also support them in listen hash.
