* Removed idea of "text" facet category (~null category) working on
all text-kinded fields at the same time, fp thinks this should be
done by defining search view fields with filter_domain
- Adding a facet to the facets collection does not trigger a search,
nor does editing the value of an (editable) facet

originally this comes from the (monkeypatch-removed) serialization and
reloading of the VS searchQuery.
This is needed because on ``SearchFacet#remove`` VS launches a
``searchEvent``, and counts on *that* to visually impact the removal
of a given facet (by just re-rendering everything)
