Mockup implementation mostly complete

Moved the splash page to a page called splash.html and created
an index page based off of the mock-up that Shelby (@ssmullen) made.
Include html5shiv from google code to handle html5 elements for IE
versions less than 9.

Primary css is included in a file called primary.css in the style-
sheets directory and includes element wide styles. These are large
site wide affects such as the basic page layout with headers, navs,
and sections.
Fixed validation problems with html

Using http://validator.w3.org/check on the various html pages so far
it turns out that the meta tags for language, web-author and copy-
right aren't valid so this commit removes them.
Merge branch 'feature/mockup' into develop
