Backbone v1.1.0 fixes

I took a stab at making the tests pass with Backbone 1.1.0.

Only two changes were necessary.

- Re-add the this.options object in the Marionette.View constructor as this is one of the [breaking changes](http://backbonejs.org/#changelog)
- Update a failing spec that depended on a private variable in Backbone.Events, which has been renamed with the new version.

Even if this isn't how you guys want to fix these issues, I hope it helps.
