Fixed #24405 -- Made admin related object JavaScript overridable 

Consolidated it in one file and move the DOM related stuff to the
template so it is easily overridable. To override the popup behavior
you need to add handlers for the custom events triggered in the
admin_change_form_document_ready template block.
