Don't read the parent when sending stream updates

When reloading the application, call the destroy methods to unbind
an event handlers, etc.

The Angular parser isn't expressive enough to handle anything but a
subset of ASCII so it's not suitable for pushing arbitrary JSON data
into the scope via ng-init. We'll have to do something else. For now,
remove it because it was just premature optimisation.

Remove source map code from vendor files

Fix error when pressing delete in empty tag field

This removes a huge dump of console warnings as the browser tries and
fails to request the map files.

Pressing backspace in the tags input still calls the removeTag handler.
This results in an exception when scope.model.tags was undefined. Now
we check for a tag and the tags array before updating.

Remove web fonts

Now using Helvitica Neue/Arial and Georgia over Open Sans and
Merriweather to reduces the size of the application payload and increase
loading times. The fonts themselves were not adding much to the overall
experience.

Convert coffee files in scripts/vendor to js, modify scripts/vendor/.gitignore

Added trivial change section

Configure updater for standalone page.

An annotation standalone page should only listen to news from
the showed annotation and its replies. This has been lost in the
our series of refactoring.

Now it is restored.

Fix #1427

Remove the util service

Move removeQuoteCharacter into an inner function of _tokenize()

This is now consistent with the formHelpers file. The baseURI method
is now available on the documentHelpers object.

Also fix a snake_case to camelCase conversion

Add ltr direction to our top injected elements.

Otherwise our text flow is broken at rtl pages.
Also remove a superfluous rule

Immediately refresh viewer for live-updates

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...

This brings it inline with the helpers.coffee, and now uses .factory
instead of .service to register the object.

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.
