Reinstate, but deprecate, the 'sleep' input (#210)

A deprecation warning is emitted if the 'sleep' input is
specified.

The value will still be used, but only if pre_sleep is either not
defined or is equal to its default value.
sleep's default value has been reset to an empty string (used
to be '5').
