Fix for throbber not disappearing on form_tag_ajax
Fix for all divs being shown as inline inside a form
JavaScript fixes:
-Make sure throbber is removed, not any other elements that may have been added after the button
-Put the throbber next to the actual submit button that was clicked
-Do not alert data if there is a callback
-Re-enable elements on window unload so they are not disabled when page is refreshed
Re-enable all inputs, not just those directly created by us
Destroy remote dialog after close - not doing this messes up some jQuery UI components
