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