Jbau hotfix 709
WIP changes for IE8 #248
IE CSS3 Media Queries Fix

After some investigation for IE8 issues, I found a better plugin that
helps IE8 render CSS3 media queries. Ref #249, #248
- Removed css3-mediaqueries.js
- Added respond.js methods
Added margin to Sign Up header, removed extra classes
Removed align=justify on landing #653
Color and style fixes for IE8 #248

- Removed CDN bootstrap-combined (using combined adds the bootstrap
responsive styles which override and causes issues with our version of
responsive.css)
- Added back hosted bootstrap.css
- Updated bg-nav.png to remove top border color for collapsed nav in
mobile
- Fixed color issues as best as possible for IE8
Updated headers for accessibility #695

- Updated stanford logo to h1
- Fixed skipped headers across base and course_base templates
- Updated left nav template to be h3 elements
Converted <i> elements to <em> elements for accessibility #698
