Our applyUpdates() puts/deletes annotations into the viewer.
But for the stream page, because there was no scope digest cycle
it seemed that the UI was reacting very slow to show the annotations.

This one-liner just creates a digest cycle in these scenarios.
The user experience is a magnitude better with this in the stream page

Fix #1455

Delete NotificationController

It doesn't seem to be used anywhere...

Remove display: run-in from thread indicators

Improve padding on #home page

Remove hover state on tabs

Small tweaks and fixes to the styled-text module

All sheet tabs now have a bottom border

Looks good to me. 

I had tried to remove it, thinking the `csrf` one wasn't used because
`identity` used `csrf_token` but unfortunately the `session` module
still used `csrf` and deleted it from the model during the response
transform. Instead, let the `csrf` value stick to the model to be
available on session object and mark the `csrf_token` value as the
deprecated one in the backend. Support for that will drop further in
the future.

Fix responsive styles when running Sass >= 3.4.

In Sass 3.4 the index() function now returns null instead of false. So
we just perform a truthy check in the respond-to mixin rather than a
direct comparison.

* Same padding to top/bottom of tags.
* Remove unused styles.
* Apply consistent padding/margins and remove extra margin above
  first line of tags.
* Update pattern library.

This is broken in Safari and removing it doesn't appear to affect the
rendering in any of the other browsers.

We're parsing the search expression for " and ' characters
to treat the text between the quotes as one unit.
But this wasn't working well, when there was a facet before the quoted part,
the quote characters were leaking into the search as meaningful characters.

I.e. tag:"no way" , the system was looking for '"no way"', instead of just 'no way'.
This has been fixed

With this proper working tag-search,
when the tag has space characters, is just adding two extra quotes.

Fix #1431

We now use the styled text module here and overwrite it to work with
larger copy.

 * Move the styled-text module into it's own file.
 * Add markdown examples to the pattern primer.
 * Fix list item, blockquote and code styles.
 * Improve font sizing of heading elements.
 * Ensure code, serif and sans-serif are rendered at similar sizes.
 * Style sub lists.

This isn't the most elegant thing. It may be time to drop
angular-bootstrap. Ah, well.

Add markdown preview, add markdown help icon, and adjust styles for markdown output

Been bugging me for some time...
