update backbone.js and underscore.js - using a gem for them now
fix backbone router specs (no need to test backbone here, just test our own stuff)
factory already returns a model...
fix url for comment model when commenting
fix url for deleting stream entries
remove the view if the model was removed
backbone 1.1.0 doesn't attach the options to the view by default anymore
hopefully fix cuke timing problem
maybe this helps with the cukes
