1. Added an accessibility page that lists the available access keys and styles
2. Moved the style switcher links to the accessibility page (should go to the control panel eventually)
3. Made the "skip to main content" visible and added the link to the accessibility page in the same block
4. Added a hidden "you are here" in front of the breadcrumbs
5. Changed access keys from letters to digits as commonly done in websites that address accessibility
