Remove rejected and initDeferred according to #540

Couldnt run tests. phantomjs times out n shit :/ 

I keept this link ( https://github.com/chaplinjs/facebook-example/blob/master/coffee/lib/utils.coffee ) in the docs to because even if most of the stuff could be solved with beforeAction today it contains a lot of goodies.  Perhaps Chaplin should offer something like the deferMethods util instead of initDeferred?
