Also bugfix: added missing username formatter

- Now it supports created search-facet
- Searchhelper rule: operator property (uses this exact operator)
- Bugfix: Space was a split value for the facet value. It is no longer one.

The previously used angularjs was buggy when the source of an ng-repeater was an array and the array was cleared and new elements where added to it after.

Stream annotation rendering was moved to streamviewer.html and can be included as a template.
Both stream.pt and streamsearch.pt uses this template.
Stremsearch skeleton page has the visualsearch widget and the streamviewer template.

- Avoid double scan at boot by passing the intended option
- Don't call domMatcher.scan directly; call the appropriate wrapper on Annotator

- When entering page search, disable dynamic bucket mode
- When leaveing page search, enable dynamic bucket mode

Support for annotating multiple frames

Closes #779

This code was moved from the host to the guest but I forgot to remove
it from the host.

Regression.

Closes #749
Closes #752

Several benefits:
- Custom open/close sidebar toggle is now possible for publishers
- The frame div holds the background image now, which means publishers
  can customize the background behind the annotation sidebar

Also, the heatmap is now the drag handle and it's finally possible to
open the sidebar via a drag action.

Closes #685
