Revision 997420

Some places in ofbiz were doing dom manipulation without waiting for the
dom to be finished loading.  Wrap such code with a dom:loaded observer.

Also, change all window->load calls to dom:loaded observers.  The former
happens after all images have finished loading, while the later happens
just after the dom has finished parsing.  This is better, as sometimes
the images may take a long time to finish downloading, and until they do,
none of the manipulation will take place.
