core (common): improved flexibility of jid selector:
- JidSelector can now display a custom set of jids, using the new `to_show` property, see
comments for details.
- a new "implicit_update" property can be set to False (it's True by default) to avoid the
automatic "update" on instance initiation. If unset, use must call "update" explicitly.
