// I take no credit for any of the code on this page.
// The original code was copied from User:TheJosh/Scripts/NewPagePatrol.js 
// User:Thingg tweaked the code so that the newpage patrol box showed up below the search box, 
// because it was annoying to have to scroll down to search if I wanted to do something else 
// while keeping an eye on the newpage log. 
// After the position of the search box was changed, I kept this because I liked where the 
// newpage thingy shows up on my display, which is 1280x800px.
