Workflow Email Notification updates:

- Added email-notification control for use in "Start Workflow" forms, it's essentially a copy of the checkbox control but defaults to checked i.e. it ignore the field.value
- Updated form config to use new custom email-notification control
- Updated form config so 'Send Email Notifications' setting is shown on workflow summary page and start task forms
- Set the 'pooled' flag for Activiti tasks when sending notification
