[svn-r11769] Purpose:
Temporary fix.

Description:
Since the file format is unstable, we don't want the snapshot tarball
be readily available to any FTP users.  Change the snapshot archived
location to a directory that is not accessible by Anon. FTP.  If someone
wants to use one of these snapshot versions, give him/her a copy of these
files.

When file format is restored, switch this back to the previous default
location.

Platforms tested:
no test since change is pretty trivial.  I have scheduled a snapshot
release tonight to see if it will put it in the right place.
