If not doing this the rootScope.predicate etc. variables are not set and angular silently fails sorting

Fixes #1150

The rootScope.annotations was not refreshed when a new real-time annotation arrived, so for comments and document view we have to insert the annotation there manually

Fixes #1149

As for the sort the page search works with threads instead of annotations so the directive should look for either annotation or thread.message in the scope
Page search focuses annotations when it opens them.

Thx @csillag for the help

Originally page search was not prepared for the sort viewState, now it is.
For this, the applySort() was refactored to use the rootScope instead of the scope and produces both the predicate for the viewer and for the page search

Fixes #1148

Page search can now search within all the scopes. Even dynamic mode works when search results are recalculated during scrolling.

Fixes #1094

This is the final piece that is needed to complete the current issues with page search quote.
I'm going to reference both issues because this and the previous commits were required to fix them.

Fixes #1095
Fixes #1103

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.
