Support flick-to-create gesture

It is a primary goal of Listless to allow a user to quickly enter tasks.
To this end, flicking down quickly should be recognised as evidencing an
intention to create a task even if the distance the screen is pulled is
less than the threshold for a shorter pull. This commit aims to do that.
