General page alerts

Created a Alerting factory for page alerts. Updated controllers to include deleteConfirm function. A few small UI additions
The messages coming from the server were not that descriptive to push out to the user so I just respond with a custom message based on the status code. I like the idea of a generic response. 

The only use-case i could think of is that if a user views a page s/he isnt allowed too it wouldn't really tell them why. I would look like the server is down when in fact they just not authorized to make requests
