My-IP6-Tool

This script is a powerfull, but at the moment very specialized, tool to dis/connect to IPv6 Networks with a wireless connection. It also could do pings and stores some IPv6 Adresses (which are hard to remember). I try to clean the specialised parts out later. This script is mainly developed by Ralf and I did only some fixes for the openMoko and cosmetics.
