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.
@erictshen you should be able to write the method for getting projects based on user. Is it giving you trouble?
