Add BW16 SD Card Example using the SPI Bus

[designer2k2]

Description of Change

This is a example on how to read a SD Card on the BW16 using the SPI bus.

Further it has a needed pin naming extension, so that external Libraries (like SdFat) using Arduino naming convention also work on the BW16.

This change also must be included to make it work: 4918cdc
