Added fall back to "webrsync" in case of failure of "rsync" Portage synchronization. Added support for GPG signed Portage snapshot ("webrsync-gpg" feature).
"emerge-delta-webrsync" is also supported and preferred.
This code require #5198
Added correct path for Gentoo iptables config file.

I would have done that by myself, but this module looks to be still under heavy development and I don't want to create new issues.
