Title: iptables-IPset  actions

This creates two actions for use with IPsets. IPsets were introduced in kernels 2.6.39 and 3.0.0 however installation on Debian machines is easy.

IP sets facilitate in kernel rapid hash based lookups of IPs.

protocol4 is used by the older ipset currently in Debian squeeze. Protocol 6 is in Fedora and Debian testing/unstable.
