   - body onresize utility (supports multiple onresize functions)
   - Robert Dominy javascript.guide@about.com many thanks
   - call SafeAddOnresize with function to load as argument,
     SafeOnresize then gets called at the onresize event,
     looping through functions.
   - N.B. overriden by <script for="window" event="onresize"> blocks
