Events: Deleting an event type

[ziggabyte]

Description

A user should be able to delete an event type. Event types are used to categorise events, and they can add up. It's important that organisers can easily remove types that are no longer relevant.

Estimated size (S, M, L)

I think this issue is S because it's fairly straight-forward and there are examples in other parts of the code base of similar actions are done.

Requirements

• Event types can be deleted
• Deleting an event type will remove that event type from existing events that have it

Possible implementations

Look at how tags are deleted for inspiration on how to do it technically!

Design specifications

None!
Is this a reasonable first step of an idea? To have a little "x" icon button after each type, that will delete this item?
