Added jQuery code and modified users controllers

To support iOS login functionality
(iOS) Added login view and now able to test if login passed or failed to the local host using json.

Changed the login function on the server side so it can send a json object to the iOS so it knows if login passed or failed (Not sure if there was another way of doing this without changing the server side). Still need to test if the session is stored and if post and follow functions work.
Added singleton class to ios to save the logged in user
got rid of virtual environment files i accidentally pushed
Added curr_user variable to appDelegate so that the currently logged in user can be accessed from anywhere in the app.
Finished login branch.

Added logout and displaying of activity/followers based on login status.
Resolved an error in the storyboard.
Merge branch 'ios-login'

Scott and Oseme collaborated to finish the branch. Noel and Ian started the branch.
