everyProperty is deprecated...

[jodarove]

On todos_controller.js, specifically in the allAreDone computed property there is:

return !!this.get('length') && this.everyProperty('isCompleted', true);

i think it may be:

return this.get('length') && this.everyBy('isCompleted', true);

Note that i also removed the double "!!"

i think also should be changed in the starting guide from emberjs.com (http://emberjs.com/guides/getting-started/show-when-all-todos-are-complete/ and http://emberjs.com/guides/getting-started/toggle-all-todos/) .
