Make templates more flexible with event categories

We listened to customer feedback and it turned out that event types were too inflexible. So we changed it 🎉

We have renamed event types to event categories and made the event categories customisable.

• You now have more flexibility using event categories within your templates to help generate context specific consent forms.
• Now instead of using a fixed list of event types with events, you can select from a dynamic list

Event categories can be anything you want, but for starters we have generated 5 event categories that map to the original event types.
