Only adaptions to print statments were needed

They are not needed and to use them is unpythonic

MFRC522.py was the only file in this project with DOS line endings

MFRC522_Init is only ever called from MFRC522's __init__ function. Move all
of the former into the latter function dropping a duplicate call to
GPIO.output(self.NRSTPD, 1).

Instead of letting the users of an MFRC522 instance clean up the resources
of RPi.GPIO, do this in the __del__ method of the instance. Also only clean
up the channel used as a complete cleanup might interfere with other parts
of a program that uses RPi.GPIO also for other stuff.

Depending on the state of the GPIO used for NRSTPD calling

	GPIO.setup(self.NRSTPD, GPIO.OUT)

might drive the line to its low level until

	GPIO.output(self.NRSTPD, 1)

is called. To prevent this spike combine these two calls into a single call
to setup specifying an initial value.
