If there is a 'www' redirect in a domain, have a flag in the automation script

We're stripping out leading 'www' in all domain listings, but some domains do a redirect to 'www', and in that case, a new mirror added won't work. So include a 'www_redirect' flag in the automation script, and send that flag to the functions that create new mirrors programmatically, so that they will use the www.domain.org as the origin.
