//javascript used to strip html coding from title attribute so it does not show on hover, but also to replace html after mouseOut or onClick so html can be used by light box.  note that Flash coding has a function to replace the html entity version of < and > (required for inline use by Ephox) with the < > required by Flash.  note that the js regular expression to find html coding requires \x followed by two char hex code for < >.  note that for IE must add title to img and change it in js; otherwise it shows the img alt on hover
