User-overridable ajax completion functions 

Moved the ajaxComplete and ajaxDone functions into the record object.  This allows for customization (which allows you to do jquery promises/deferred, etc).  To override, create a handler to respond to the dynatable:preinit message and swap in your ajaxSuccess and ajaxDone functions.

$('.dynatable').on('dynatable:preinit', function(el, dyna) {
  dyna.settings.ajax.ajaxSuccess = yourSuccessFunction;
  return dyna.settings.ajax.ajaxDone = yourDoneFunction;
})
