remove INPUT_PULLDOWN for GPIO16?

[mhanuel26]

on version 1.6.4-673-g8cd3697, this instruction compiles and works correctly

pinMode(16, INPUT_PULLDOWN);

On new release, I got:

REMOTE_SENSOR_ONE_WIRE.ino: In function 'void setup()':
REMOTE_SENSOR_ONE_WIRE.ino:490:15: error: 'INPUT_PULLDOWN' was not declared in this scope
REMOTE_SENSOR_ONE_WIRE.ino: In lambda function:
REMOTE_SENSOR_ONE_WIRE.ino:680:40: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
'INPUT_PULLDOWN' was not declared in this scope

I think that pin16 must be pull down via INPUT_PULLDOWN_16
check line 68 core_esp8266_wiring_digital.c
so...README must be changed

Thank you.
