now compiles for Arduino Due - but has initialization failure
fixed problem with printing diagnostic info (IP addresses, etc.) on Arduino Due
switched from using _VARIANT_ARDUINO_DUE_X to using __arm__ and __SAM3X8E__ to check for Arduino Due or compatible systems
switched from using _VARIANT_ARDUINO_DUE_X to using __arm__ and __SAM3X8E__ in header file
changed SPI_CLOCK_DIV2 to SPI_CLOCK_DIVIDER in cc3300 object creation to allow higher SPI bus speeds on Arduino Due
updated pin/interrupt table to include all Arduino Due pins
Merge pull request #49 from adamfeuer/arduino_due

add support for Arduino Due
