Maurice Williams fb170d1725 Pagination for Users Management screen
closes #3222
- implementing server-side pagination for /users API
- passing /users?limit=none will return all users
- passing /users?status=invited will filter base on user status
- creating 3 mixins (route, controller and view) to keep pagination logic DRY
- updating route, controller and view for Posts to use new mixing
- implementing infinite scrolling for Users Management screen (using new mixins)
- Users Management screen displays all invited users, but paginates active users
