Authorization features added

This patch uses Django's middleware to implement authorization in adagios.

To enable the patch you need two things:
* In adagios settings make sure to enable authorization

* If you want administrator access make sure the following is in adagios.conf:
administrators = "user1,user2,group1,group2"
auth - remove anonymous from administrators role
authorization - update default rules
403.html now includes helpful docs
