Add basic authority browse/edit/delete interface

Add basic authority browse/edit/delete interface

http://localhost/eg/cat/authority/list should get you where you need to be

The paging is comical, the JS should probably be split out from the
declarative markup, the interface needs i18n, the UI needs to become
usable - but at least we have exposed some functionality for working
with authority records now.

Ideally this becomes a widget that we can just embed into other
interfaces to maintain context (which suggests using openils.cgi
to seed the initial values of the widget).

Note that the delete function works - it sets the deleted flag for
an are to "true" - but the underlying authorities browse interface
currently doesn't care about such niceties and always returns deleted
records along with undeleted records. So that might be the next stop.
