Iptables-tutorial 1.1.15 release
Version 1.1.15 of the iptables-tutorial fixes a lot of old spelling mistakes, as well as a lot of other minor bugs. The biggest change is that the save and restore chapter was now added properly to the tutorial, and can be read. This was previously forgotten, but should no longer cause any problems. Specific thanks go out to Robert P. J. Day and Otto Matejka for their help on various problems.
