Add triggering of actuator on/off state by button press.

This will enable using button on the gateway to switch any controlled attached actuators/relays when pressed.

Adds the following macros:
- ACTUATOR_ON; 0 or 1, set to the output level of the gpio pin to turn the actuator on.
- ACTUATOR_ONOFF_DEFAULT; ACTUATOR_ON or !ACTUATOR_ON, set to the state desired on reset.
- ACTUATOR_BUTTON_TRIGGER_LEVEL; 0 or 1, set to the sensing level which to detect a button press to change the actuator state.
