Undo Modechanges

This script is supposed to undo all modechanges in a channel. It may not work 100%, but it will be updated in the future. You can find explanations in the script.

Note that you cant just replace + with - and - with plus as e.g. +l needs a parameter for setting (the limit that is), but you can unset it without parameter (just -l). Read more about it here.
