Trigger an enduring event.
Does nearly the same as :meth:`!TriggerEvent` but the event will not be
ended immediately. This is used for devices that can have longer
enduring events, like a remote, where you can press and hold a button.
The plugin has to call :meth:`!EndLastEvent` to end the event. The last
event will also be ended, if another event will be generated through
:meth:`!TriggerEvent` or :meth:`!TriggerEnduringEvent`. This will
ensure, that only one event per plugin can be active at the same time.
