Set up Profile VC
Merge branch 'master' of https://github.com/siska/InstaPro
Setup Root VC for login and sign up.  Not sure how this connect via segue just yet so I didn't change the initial view controller arrow so we can still see the rest of the app.  I also set up the newsfeedcontroller and connected the appropriate outlets.
