Enhance the dashboard. (#262)

* Update to a more flexible admin authentication
* Admin can now access any project
* Add delete and edit options in the dashboard
* Add a link to the dashboard in the nav bar

This is a rework of the changes proposed by @Olivd, so they can apply on top of
the latest master without trouble. All credit goes to him for the code.
