[ale] Site updates for AsciiDoc; more example links?

[David Hilvert]

Transition to AsciiDoc for site pages has begun, with new pages stored in
/doc/web in the git hierarchy.  'checkout mob' to edit, and push any changes to

git+ssh://mob@repo.or.cz/srv/git/Ale.git

Updating the 'Examples' section on the main page with links to off-site media
might be useful, e.g., linking things such as

http://commons.wikimedia.org/wiki/Image:A_wasp_eating_a_fly_DSCN2740_stable.ogg

(I don't yet have a video camera, so I haven't posted any video examples of my
own.  Any still image examples would be useful also, of course.)
