Major change to the javascript forum view.  We now wait for all messages to be loaded before rendering them all in one shot.  Rendering works, opening the reply box works, saving a message works, but we still have to figure out how to render a message in the location where it was entered.  Or maybe that's not a good idea?  Also the scroll_to semantics are broken but we are in a better position to redo this in a simpler way.
