More responsive layout, better mobile view

- now scales font size up and down depending on viewport (hello real responsiveness)
- ups font weights and sizes slightly on small devices (looked a bit funky)
- remove the attempts to make header sticky (this is unnecessary and didn't actually work)
- move apple-touch-icon meta tags to their own include file
- move copyright paragraph to its own include file, and add it to redirect page
- sync redirect page with main page layout and style
- improve readme
- add dotfiles, bookmarklets, phidgetty, Chrome Installer and WebKit Updater to examples page
