Fix doc comments for devel version

Don't say version 0.0 in the emails that are sent out. That's what we
call it internally, but the URL should have /devel/ in it. Fix this both
in the template, and then if it comes through in the form again in case
the user picked up a link elsewhere that is incorrect.
