So I discussed this with ettore and hans offline and we think these
should actually be named properties on the backend.  In this scenario,
the backends should probably be given the source uid rather than the
uri, because they will need to grab the named properties for connecting.

The main issue here is the GUI for some individual backends.  For
instance, where will the LDAP backend gui come from?  and will it be
readily available to outside developers?  I'm reluctant to put the gui
bits into e-d-s but it may logically be the only place to put them.  I
suppose we could have some sort of generated ui, but those tend to
degrade over time.

The delete method is already on the backend, I think probably the rename
method should be too.  Then the backend can handle the actual rename,
which is useful for groupwise and exchange.

For copy we can probably create a new calendar then fetch all the items
and save them.
