GPIO channels are not closed on Ctrl+C termination

[ptodorov0]

If you terminate alarmd.py or keypadd.py with Ctrl+C or Ctrl+Z and then relauch you will see that the GPIO channels cannot be reopened because they are already in use. My solution was to add

include signal
include sys

... and just before the "while True:" ...

def signal_handler(signal, frame):
    print '[EXIT] You have just terminated the script execution!'
    io.cleanup()
    sys.exit(0)
signal.signal(signal.SIGINT, signal_handler)

Change "io.cleanup()" to "GPIO.cleanup()" in order to use it in keypadd.py.
