[Box-Admins] Release directory protocol

[Frank Shearar]

Someone's asked me to remove the old release candidates for 4.4, which
seems like a good idea - the reporter said it looked confusing. So
I've deleted all files in /var/www/files/4.4/ except for
Squeak4.4-12327.zip.

Just in case you're wondering where those files have gone.

I'm happy with the idea that subsequent 4.4 releases go in that
directory (and stay there), but a periodic cleanup of alpha or RC
images seems sensible?
