appFinish() double fires in Firefox, Safari

This issue is a side-effect of #259577: integration with Fckeditor (type of link not changed to 'other' , in which a second line of triggers was added. We currently have these two lines of code:

    try{doc.find('#'+ appFields['url']).blur().change().focus()}catch(e){};
    try{doc.find('#'+ appFields['url']).trigger('onblur').trigger('onchange').trigger('onfocus')}catch(e){};//inline events

The problem is that the first one only fires in Firefox, Safari, or other respectable browsers. The second one fires for ALL browsers though, including versions of IE, Firefox, and Safari. The end result of this is that the events fire twice in browsers that work with both implementations.

Rather than using both approaches, deleting the first line makes it so that only one approach is used, which works in all browsers. In my particular use-case, I have an onchange function that triggers an AHAH request, so firing twice generates an unnecessary HTTP request.
