person*.firstName = "Manuel" uses Ember.set

this can also bee seen on the website.
When *. is used, it should be set directly like person.firstname = "Manuel"

I think this worked in earlier versions

this is actually worse than i thought. I want to set some global variables on window but it doesn't work because of this and Ember.set seems to have problems now when the object is window
