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

- The directive now determines the timezone
- Determines the browser language settings
- Adjusts the time to show in the tooltip with the timezone difference
- Formats the timestamp according to the detected language
- Uses jstz, momentjs, and moment-timezone

The fuzzytime directive's template has been modified to turn the timestamp into a link for the annotator's standalone page.

Fixes #1008

- Now if a realtime update arrives, the tab numbers are recalculated
- The new (or updated) annotations' parents  are marked with the _updatedAnnotation property
- The new blinkBuckets() function in the heatmap checks for these annotations and does the blinking in the relevant buckets and removes that property (so only one blinking will occur)
- This new property is transferred via the bridge plugin

It makes more sense to compute this when its value changes, rather
than at the time the share button is toggled

* angular-animate.js library was added to the project (as a file, and to assests.py and app.coffee)
* The ng-repeater tags for annotations in both viewer.html and page_search.html were enhanced with the vl-animate class
* This vl-animate css class contains the animation description in the common.scss (currently emulating a 3D cube change)
* The update notification bar is no longer active.

Scope cleanup part 1

Fixes #1099

User visible:
 * Introduced the "Tab", "Selection" and "Comments" views, as per #1091
 * Fixed the following problems:
   * Clicking on a tab does not update scope name
   * Clicking on a highlight does not update scope name
   * Clicking on heatmap does not update scope name

Internal:
 * Change function names:
   * applyview -> applyView
   * applysor -> applySort
 * Move the `view` field from viewer's scope to rootScope
 * The `updateViewer` and `showViewer` methods of the Hypothesis class
   no expect a `viewName` parameter (alongside the list of annotations),
   which they use to update the `view` field of the rootScope.
 * Added a `getComments` RPC call in guest, to collect comments for comments
   scope.

Like #1096, this is an angularjs upgrade issue too, which was already fixed once, so strange.
