This is a replacement for Ajax.Updater, as we want to replace an element not update it 
The only changes are this line:

receiver.replace(responseText) - changed from receiver.update(responseText)

And this:

if (!this.success()) {

Which allows us to handle failed page loads with an alert, 
and we don't have to worry about it updating elements with .NET error text
