!!! - THIS IS VERSION 3 OF THIS SCRIPT - (despite the name...)

inserts content into top of DIV#utilities rather 
than replacing default content in a known DIV ID.

version 1 is still (Jan 2010) in use but can be 
discontinued if those pages already using it are 
ammended to use this one (including removing the 
specids-of-day utility fragment).
