Moving eventCast()
In a situation where you have an EventPtr that you want to place
somewhere as an `event_ptr_tt<SomeMoreSpecificEventType>` you have to
carefully check that the stored event is actually of
SomeMoreSpecificType and if it is, release() that event pointer,
downcast, and re-wrap it into that new event_ptr_tt - or, as can be seen
from the diff here, re-loadEvent() from JSON, which is simpler but
inefficient. To help clients, and the library, eventCast() can now
accept an rvalue smart pointer and do all the necessary things with it.
