+- Added driver for Samsung VFD displays from Adafruit
+- Added average sampling option to projectconfig.h.
+ This allows you to take several readings from the
+ ADC and return the average. Helps reduces one-off
+ peaks and valleys in the ADC at the expense of
+ slower reads.
+ See: "tools/validation/adctest" for more info
+- Added I2C driver for PN532
+- Updated and added PN532 examples at
+ /tools/examples/sensors/PN532
+- updated touchscreen.h to be a bit clearer during
+ calibration, though it can still be much better
+ organised
+- Had to add "__asm volatile("nop");" after pin writes
+ in the ILI9328 driver since some LCDs couldn't
+ keep up with the high-speed writes with bit-banding
+- Fixed I2C clock duty cycle registers
+- Changed I2C buffer size from 32 to 64 bytes (i2c.h)
