Title: don't forget liquid updates for unloaded blocks (fixes #424)

when a liquid update is attempted in an unloaded block, reschedule the
coordinates of the nodes for later, so the liquid update is done when
the block is loaded again. Previously, the coordinates where simply
forgotten and no liquid updates where done when a block is loaded
again.
