Activities TVC: initiated integrated GVC properly

Admin Mode:
Added some initial files for admin mode and edited LoginVC accordingly
Added a new masterVC for the admin part, but this is not working yet. Edited appDelegate accordingly.

Integrated GVC: Now does initial scrolling to selected exercise. Code is there to load both of ZY's plots, but crashes due to one of the plots.

MasterViews: Added a blank master view before the existing complianceFormMasterVC in the navigation stack

VideoVC is now linked from integrated GVC.
