The previous fix introduced handling the page search quote search facets as list.
However the empty list was not handled well. This correct that.

Collect all quote items for Page search.
I'll merge my PR because it is an easy fix. Not affecting anything else.

Originaly visual-search automatically collects the text fields into one space separated list.
But it does not do the same for any other field type, so we have to collect our search facet's values for quotes manually.

This changes now expects that our quote search results are a list and handles it like this all the way. (Even for generating the highlightQuote attribute)
Now if multiple query facets are given it assumes an 'AND' relation between them.

A nice future task will be makes this page search configurable as like the stream facets, but that should come after viewer/page search unification

Introduce focus

Missing: search magic

I think this better ensures #1135 is fixed cleanly. Before, the
controls might hide after the timeout, but the user may be on their
way to click it. Now, everything goes through showViewSort, and it
manages timeout cancellation.

Also, moved the view and sort controls out to the app.pt. Because
they're essentially global now, and we should move to kill the viewer,
editor, search distinction anyway.

Also, use destructuring while we're here for readibility

Coffee always breaks switch cases

Moved `applyView`, `applySort` and `viewState` to the root scope.

Fixes #1131.
Fixes #1132.

Fix #1123

Multiple selections

The way to avoid it is to just handle the view switch entirely in
the sidebar, rather than consulting the heatmap, if comment view
must be activated.

Improve CSS for viewsort controls

Pressing Ctrl (or Compose), and clicking on a highlight,
or a tab on the heatmap now adds annotations to the current selection.
A second such clicks removes them agian.
