bug fixes

1) Simple typo of variable name.
2) Permissions was assuming all resources were of type UserGroup.
Changed it to call super when this wasn't the case.  Also some documents
were coming in as RDF docs and some were coming in as dicts.  I added a
check to convert dicts to RDF docs.  Perhaps this isn't correct though
as it's due to a bug somewhere else?
fixed a couple of bugs in ac permissions logic
fix new site dialog
Set user in headers, returned permissions after check

1) intra_system_get doesn't seem to set the cookie for the current user
(they show as anonymous on the other side of the get.
2) if the user had permissions on all resources we were their
permissions on ac which isn't right.  I changed it to return full
permissions.
