Add support for GCC_ARM toolchain in target STM32F103RB
Removed BLE related code to github

As part of transitioning to mbed.org, the BLE code is now only available
on mbed.org:

http://mbed.org/teams/Bluetooth-Low-Energy/code/BLE_API/
http://mbed.org/teams/Nordic-Semiconductor/code/nRF51822/
remove BLE related tests;
They were only demos; not real tests.
SD card test updated with 11U68 pinology
Added pins for EEPROM line test
[NUCLEO_F302R8] SPI master corrected

[NUCLEO_F302R8] SPI master correction
Changed LED mapping to RGB

Changed the pin mapping for LED1, LED2, and LED3, to Red, Green, and Blue respectively. This matches the KL25Z, and makes more sense in my opinion.
