This PR fixes the parsing of the GPIO commands so that a ":" is allowed as the "=" gets stripped. It also addresses a defect when there were two arguments to the command and the second was being dropped. Something like GPIO4:1 will now turn on the GPIO4 pin. GPIO4:0 will turn off the GPIO pin. LEDs should now behave correctly.
