Faster dropdown animation for publish button

Closes #4390

- Apply same animation timing from the nav bar dropdown to the publish button dropdown
Cleanup User List styles

No issue

* Cleans up the Sass a bit
* Uses the same basic markup as other settings pages. Before, we had extra elements which required 'reseting'
Remove .eot & .ttf fonts

No issue

According to [caniuse](http://caniuse.com/#feat=woff), all the browsers we support (last 2 versions of major browsers) support the `.woff` font format. It's actually what pretty much all browsers will serve if its offered anyway.

This PR removes the .eot and .ttf font formats.

SVG remains as its the base file we use to add new icons & convert into other formats. It is not referenced anywhere.
