extend dimmer stepping so the step size can be specified in the command.

this allows things like "DIMMER +20" to increase the dimmer value by 20,
and "DIMMER -40" to lower it by 40. 'DIMMER +' and 'DIMMER +' keep their
current behaviour.

this is useful if you're using something like a zigbee remote that
generate a single message with how much of a step up or down to perform
as part of the payload rather than multiple messages.
