Contains page with overview of partners
Contains admin of partners

This should probably be replaced again soon by something nicer,
but this is functionally equivalent to what we had.

This is still wants a nice admin back-end;

This also wants a few more tweaks in the front-end,
solving some CSS problems and adding album pagination

See #13

Closes #12

Includes tests and an authentication backend to check the permissions
granted to committees.
