Jon Trulson 6793c892ed sm130: Complete rewrite
This is a rewrite of the existing SM130 driver which was incomplete
and non-functional.

It was implemented using a Sparkfun SM130 module:

https://www.sparkfun.com/products/10126

... using a Sparkfun RFID Evaluation Shield:

https://www.sparkfun.com/products/10406

It operates in UART mode only.  A port to support I2C communications
(requires a encrypted firmware reflash from SonMicro) should be
fairly trivial, if you have one of those.
