Updating the footer for edx.org and open edx.

Making the footer look more like the front page.

* Updated SASS for footer
* Updated HTML for open edx and edx.org templates
* Updated stubbed views
* Added !important SASS to overwrite some blanket LMS styles

Updating steve.m.sandbox.edx.org to have the latest changes.

Good point. Also looking back at the screen shots for the proposed design, it's supposed to be two separate links (though there is only one page for TOS and Honor Code) @griffresch @andywaldrop Any suggestions for this?
