A day of patch-o-matic-ng merging

Since there are slight syntactical and semantical differences in the API for iptables matches and targets between 2.4.x and 2.6.x kernels, a minimum editing has to take place in order to make even the most simple 2.4.x extension work with 2.6.x. With more than 65 extensions in current pom-ng, this can take quite a while.

Apart from a minor bug in the Netfilter_POM.pm perl module, we should now be ready for the first official pom-ng release. Finally, people will be able to use our extensions with a 2.6.x kernel.
