/*
Following 2 functions move elements up / Down in a select list (http://www.breakingpar.com/bkp/home.nsf/0/87256B280015193F87256C5F00602363)
Both functions are pretty straightforward. First, make sure it makes sense to move 
the entry (if there's only one value, then there's no sense in trying to move it) 
and make sure the user has selected an entry. Second, make sure the item can be 
moved (the first item cannot be moved up, the last item cannot be moved down). 
If the item can be moved, then swap the text and value with it's correct neighbor. 
That's it. Here's the "move up list" function:
