Add Catalyze

Significant changes. Added Catalyze framework after git revert all the Parse changes. Put login stuff on the main VC and created a separate signup view controller. Implemented basic validation logic and login functionality.
Add TPKeyboardAvoidingScrollView

Added an external package to assist with moving the scrollview when keyboard covers it in signup view controller.
Remove old scroll view code
Minor changes

Capitalize username string. Add additional error message on signup.
NOTE: Signup is currently unsuccessful, cannot determine why. 400 error bad request every time I try to sign up. The app handles it gracefully, but no users can login yet
