Works with IDE 1.6.12 and ESP_ARDUINO release 2.3

[Defragster]

I just powered up an ESP8266 unit connected to a Teensy and both are programmable with the IDE 1.6.12 and compile of nailbuster/myWebServer with ESP updated to release 2.3 update from 'Boards Manager' worked for OTA updates (until I forgot to double check Tools and my 3MB SPIFFS was 'defaulted' to 64K with 512KB for code) - so not enough room for 311KB sketch, and I lost my data.

Not tested extensively beyond a few OTA's before the IDE broke me - I now need to get back to a Serial upload through Teensy to get OTA back online.

Some notes I made for this update here as I work with a new Teensy and PCB with an ESP8266 mounted - with options for Teensy to have display and added external Flash and RAM:

I did get these compile time nuisance warnings:
