Update page to be Origin focused project page

This commit includes the updated index.html and all the supporting
asset files for the first draft of the page.

Background: Since we are automatically building the Origin
documenation as a subdirectory, we want a corresponding landing
page to serve as an open source project page just like any other open
source project hosted on GitHub. The purpose of the page is two-fold:
to point to the documentation and to give a overview of the project.
Remove references to outdated LiveCD

LiveCD is apparently very old, so we're taking away any references
to it and we'll update the page with VM images when they're ready.

Also updated styling as needed to accomadate the change.
Add custom typography styles to Yard docs

Added custom font rules to the common.css file in the Origin Yard
docs to help the docs look a little more like the project page.
Cleanup redundant fonts folder
