Admin and ambassador dashboard

Basic view for the admin and ambassador dashboard. Added a review page, and views for proposed and edited projects.

As of right now, it is incomplete, and does no user verification. Also, the review page is the same for both ambassadors and admins.

Note, the review page might not have been implemented in the best way, let me know any comments on how to implement this better.
One way to query against the user is to make another method get_user_projects which takes a user and queryset and returns all projects where the user field matches this user. You can pass the return of get_drafted method into that one.
