Add Summary field to "Event: Create or update" action

Hi Jaap, I hope you are doing great. For Barnekreftforeningen, we have created a new Form processor and from "My page", we are creating events. Everything works fine, but the summary not being populated from the Form processor actions because it is not listed in the event fields.

All that needs to be done is: List the field in the action Line 54:

new Specification('summary', 'String', E::ts('Summary'), false, null, null, null, FALSE),

Populate the field after line 130 add following:

if ($parameters->doesParameterExists('summary')) {
  $apiParams['summary'] = $parameters->getParameter('summary');
}
