Support for NodeMCU R2 boards

[Lenbok]

I have just got a couple of R2 boards, and uploading to them from the IDE does not work.

According to http://www.electrodragon.com/w/ESP8266_NodeMCU_Dev_Board#NodeMCU_1.0_.28ESP-12E.29 flashing needs a couple of parameter changes compared to the r1 (SPI SPEED choose 40MHz, SPI MODE select DIO, FLASH SIZE select 32M)

For my lua code, when I flash nodemcu firmware I need to supply esptool.py with -fm dio -fs 32m parameters to get things working.

If the arduino IDE could add a new board entry that set the equivalent parameters when uploading it would be great!

it's already in the trunk. Here is the config for you to add it if it's still missing from what you have

Thanks, I have 1.6.4-673-g8cd3697, via the IDE boards manager, I'm not sure how old that is, so will manually paste that text into the boards file I have.
