Pressing Ctrl (or Compose), and clicking on a highlight,
or a tab on the heatmap now adds annotations to the current selection.
A second such clicks removes them agian.

- 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* The update notification bar is no longer active.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.

Fixing the fix for the #1065

Search refactoring 1 - try 2

This does the following:

 * Introduces the `viewFilter` service, to filter annotations according to a given query.
 * Factor out the filtering code from the controller into this new service. (As described in #1092)
 * Enhances the tab searching: now we can search for multiple tags.
