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.
I didn't make the helper method, when getting drafted projects based on a user, I just passed in the specific queryset.

        owned_projects = Project.objects.filter(ambassador=self.user)

Will update the pull request (@ 7 or so when I get back from OASES to add that helper method)
