fix typo in a comment
Merge pull request #245 from philfreo/backbone-0.9.10

Toward Backbone 0.9.10
Add "and contributors" (linking to github) to the copyright statement
Fix test #3 failing sometimes, depending on test ordering.

Caused by some tests creating an additional (reverse) relation on `Person` for `Password`.
Add a (simple) test for passing `silent: true` to `set`
Remove the override for `Backbone.Model.change`, since it has been removed from Backbone. Partial fix for #244.
Insulate `super/subModel` tests better from each other using a model `scope` instead of `window`, to prevent test execution order from influencing the outcome.
Modify attributes directly, instead of calling `set`. Partial fix for #244.

This prevents Backbone 0.9.10's reworked changed/changedAttributes/previous machinery from being triggered more than once, thus setting incorrect changes.
