Adds {1ep:n} parameter to motor object to invert enable polarity for …

…use with external drivers.

NOTE: This candidate does not have motor typing or lockout features to disable on-board drivers if EP is set for external drivers.

// Fix UART flow control

Power management fixes

// Fixes for UART at the wrong baud rate on Sam3x

// Added _leds to drive the neopixels

1 = white

// Fix for NeoPixel output frequency being doubled.

In fact, all PWM peripheral based pins had the frequency doubled. This was fixed mostly in Motate.

// Fix for inputs causing a crash (again).

If the GPIOs on the board don’t provide all 12 inputs (most don’t) then it would occasionally crash when resettings the first pin past D_IN_CHANNELS. This is fixed.

Fix for inputs causing a crash.

Due to the construction order getting messed up, the inputs would crash on interrupt. This has been fixed.

Fix to 100.00 not resetting properly.

• When connecting over USB, 100.00 would not complete the reset into the SAM-BA loader. This is fixed now.
