Add angular animate library and real-time update new annotations

* 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* The update notification bar is no longer active.
Handling realtime updates (no animation just yet)
Realtime update for deleted annotations
Blinking tabs on realtime updates

- 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
Adding permalink to timestamps

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

Fixes #1008
Permalink timestamps in the standalone pages and the stream page too

For the permalink generation the annotation id was necessary. However our viewer has stored this differently, so that the permalinks were not correct either in the standalone- nor in the stream page.
Now the directive checks for the annotationid property of the element and if it exists it uses the id from there.
Also the URI generation has bad for the standalone page. This has been also fixed.
Fuzzytime directive gets title to show exact time as a tooltip

- 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
