Refs #168. Refactored PageProfile2 view to use API. Current version of the view uses:

 1) Profile api to query:
   - users
   - boards
   - pins
   - update profile views
 2) Soical API to query
   - followers
   - follows
 3) Notifications api to send notifications to a given user

The migration does not include function responsible for categories rendering: categories_to_select
