0.9.19 - attempted fixes for witch crowning glitch

sometimes the witch crown is not detected, even if it lands perfectly:
the witch damage array is present; the crown is not marked as 'bungled';
it does not register as a oneshot and the crown type is 0 (not shotgun)
-- even though it is.

Attempted fix: delay crown check, so the ontakedamage post call gets
more time to fire.
