With its confusing and limited behavior, along with its not so great icon, this markdown button in the editor wasn't so helpful. People who are likely to insert code into a markdown post to begin with, likely have a good idea of how to already do that or where to find information on how to code in markdown (there is also a link next to the preview button).

The assertion is not what we want, nor is the argument that is passed
to the `withToken` callback (which is the payload). We want the encoded
token string, which will be inside the Auth plugin.

Improve viewfilter

Remove focus state when clicking on toolbar buttons

Update Firefox extension

Remove unused h.notification.domain_mailer

Backend has changed to allow this a long time ago,
and as stream page performs frontend filtering too,
backend results weren't shown.

Fix hit area for dropdown menu items

Build production versions of the extensions on Travis

Now all items contain anchors which are set to display: block this
keeps all implementations consistent and improves accessibility.

Add MathJax config option allign left.

Previously, MathJax was rendering display style math allign: "center",
while KaTeX rendered allign: "left". This has been addressed.

When the showHighlights option is passed to the guest constructor as
we do with the extensions.

This prevents the focus style continuing to be applied after a toolbar
button has been clicked.

Fix tag search.

This escapes any special url characters in the term

ES stores the tag field as tags

Fix #1879

This contains some potentially confusing code and was clarified by
Randall here: http://git.io/HvLCLA

Set the standalone conversation as the viewer root

This special cases the threads that are styled as cards rather than
replies and allows them to be styled accordingly.

Now the thread is not using negative margins this isn't required.

Fix #1803

Replace documentHelpers with baseURI + URL API

Rather than have a service, ``documentHelpers``, that exposes a value,
``baseURI``, and a function, ``absoluteURI``, decorate ``$document``
so that it's guaranteed to have a ``baseURI`` property and use the
previously included ``URL`` constructor as a standard way to get parts
of a URL.

For readability, especially in light of the injection annotations,
split the app configuration functions in ``app.coffee``.

Clean up unused and duplicate TextHighlight code.
