Add per event-type message templates / defaults

[JPustkuchen]

The messaging system via courier is very cool! But I think it would make a lot of sense to make it possible to define message templates and default messages for events:

Like for example on a path like this: admin/structure/rng/event_types/manage/node.veranstaltung/messages

A form should be available which predefines the message defaults for all events of this type like on https://www.ife-owl.de.preview.webks.de/node/XXX/event/messages

When creating a new event these templates should be cloned into the event so that they can be changed / overridden, if required. Otherwise they will simply work like configured.

Is there still no way to setup default messages?
