Linkify ting

// This script looks for any thing of the form
// [something not blank][a dot][something not blank], 
// then matches that which comes after the dot - and possibly before a slash - 
// with a list of know extensions, such as com, us, net etc. 
// If it has such an extension, it is turned into a link. 
// This way the script attempts to catch links like
// google.com and userscripts.org/tag/link.
// Because the script looks up extensions in a list, 
// you might want to alter the list (lovligeEndelser) to fit your needs. 
//
// The script is borrows a bit from the ÂLinkify PlusÂ script 
// (especially the parent not a | head | etc -  thing). And therefore the following 
//
//- - - 
//
// Loosely based on the Linkify script located at:
//   http://downloads.mozdev.org/greasemonkey/linkify.user.js
