R6. Statement about proftpd.org and proftpd.net.

The www.proftpd.org and www.proftpd.net sites now should be effectively
mirrors of one another. The official proftpd site is www.proftpd.org,
however www.proftpd.net will remain in operation at a physically remote
location in order to provide redundancy.
