Fixed Bug 1014765 and Bug 1019640

In the Webmaker.org footer, in the line of text "with support from our wonderful partners and Mozillians like you!" ––  the word[Mozillians] should link to `https://mozillians.org/en-US/`

Also fixed an additional mistake in the `webmaker.org.json` file and `layout.html` file, regarding the spelling of "Mozillians".

Also Fixed Bug 1014765 and updated the font-awesome to 4.1.0
