Turn Stream into App

This refactor turns the stream page a part of our main H application

Main features:
* Stream is now accessible from our app at the /stream angular route
* Stream has the same header (same look, same code) as the main app
* Authentication from the stream page is now possible
* The same visualsearch-bar is used both for page- and stream search
* Stream page now uses our viewer.html to show annotation cards.
* Replying to/editing/deleting annotations can be done in the stream
page too.

Details
* streamsearch.pt is obsolete and has been delete because app.pt is
used instead of it.
* streamviewer.html is obsolete and has been deleted because
viewer.html is used instead of it.
* The QueryParser class is moved into the streamfilter.coffee and
available is a new service for the app.
* The visualsearch directive now uses functions living in the
<current scope>.search object that any part of the app can configure it.
