DigitalOutputProtol Drivers: add invert method

Adds the invert method to the various drivers implementing the
DigitalOutputProtocol.  Specifically DeditecRelaisDriver,
FileDigitalOutputDriver, GpioDigitalOutputDriver, HttpDigitalOutputDriver,
LXAIOBusPIODriver, ManualSwitchDriver, ModbusCoilDriver, OneWirePIODriver,
SerialPortDigitalOutputDriver, HIDRelayDriver

Adds the invert attribute to the GPIODigitalOutputDriver and  the
GpioDigitalOutput agent.
