Updated backbone script to v1.1.0
Re-added this.options to the View base class

In Backbone v1.1.0, one of the breaking changes was to no longer
automatically assign the options hash passed into Backbone.View to
this.options.

This change caused things to break in lots of places where
[Marionette.getOption](https://github.com/marionettejs/backbone.marionette/blob/master/src/marionette.helpers.js#L27)
was called since it looked for things to automatically be added to
`view.options`.

Example:
[Marionette.View#getTemplate](https://github.com/marionettejs/backbone.marionette/blob/master/src/marionette.view.js#L26)
will work if you define the template through extend, but will fail if
template is passed as an option.

This change re-adds the assignment to `this.options` in the
Marionette.View constructor. This effectively solves the problem, though
perhaps a more extensive solution that doesn't try to knee-jerk re-add
previous behavior would be preferable.
