/* Sysop decrier/detector (rights group displayer), version [0.2.1]
Originally from http://en.wikipedia.org/wiki/User:Splarka/sysopdectector.js

Notes:
* Fixed this up to use the new API fun stuffs.
* Shows all groups now
* nstab-user isn't available in all skins, all skins have at least one h1 or h2 I believe.
* heading given class="detected-userrights-heading" and text in span class="detected-userrights"

Options:
* Now supports an option system.
* By setting a datalet true it shows in the header instead of the title.
* Note, all are assumed false if omitted. All but 'groups' are assumed false if undefined.
