Wrong eventname in documentation of events example

[Friksel]

The markdown doc contains a wrong event-name for interrupted animations (so probably the example is also using the wrong eventname?)

The interrupted event doesn't exist and I've tested it; it also never fires. The real event name is interrupt, which in fact does fire.
