to avoid that the comobox triggers automatic API request with the
queryParam default `query` GET param on manual typing (e.g., for
filtering) from the user, we have all data already loaded and locally
available.

add a default namespace selector (of the current default store)
and a namespace selector per target datastore (for media-sets with
multiple datastores).
to achieve that we have to change the way we handle the mapping field a bit:
* don't use it as field directly (otherwise the value gets stringified),
but use the 'getValue' method in 'onGetValues'.
* set the defaultStore there, not only that we have one
(with this we can now easily show it as emptytext for each store)
* add a reference to the widgets to the record so that we can access
them in the respective change handler (also clean those references up,
else we have a cyclic reference between record <-> widget)
in onGetValues, if we have multiple datastores, the mapping grid does
all the work for us, otherwise, we have to create the ns mapping
ourselves there.
