Fixes issue: https://github.com/kanaka/noVNC/issues/155

noVNC.com is really the preferred URL that will redirect to the real
location hosted on github.

Also update the Authors/Contributors section to mention Chris Gordon.

Update the screenshots to show the new user interface and mobile
device support.

Move the old demo videos to the bottom and shrink them slightly.

Still list companies but move the extra info to the wiki.

Broadway uses noVNC keyboard/input handling. Link to it.

Separate the links from each other so it's obvious where the links
are.

Symlinks don't work.
