ESP8266 ESP-01 with AT version:0.50.0.0

at first, i am just so happy it finally works, had some problems with an apparently faulty esp8266

after that bad start i ordered some esp8266 esp-01 from eBay, by especially searching for "...tested..." and i got one with the following firmware:

"AT+GMR\r\r\nAT version:0.50.0.0(Sep 18 2015 20:55:38)\r\nSDK version:1.4.0\r\nTested in UK by AudioSpectrumAnalyzers\r\nOK\r\n"

well to get it working with an Espruino Pico i needed to change the ESP8266_v025 module in one little detail

from

if (d=="ready")

to

if (d=="Ready.")

here is a larger part to see the change in context

"reset" : function(callback) {
    at.cmd("\r\nAT+RST\r\n", 10000, function cb(d) {
      //console.log(">>>>>"+JSON.stringify(d));
      // if (d=="ready")...
      if (d=="Ready.") setTimeout(function() { wifiFuncs.init(callback); }, 1000);
      else if (d===undefined) callback("No 'ready' after AT+RST");
      else return cb;
    });
  },

ok now to my question, do we want a special ESP8266_v50 module? if yes i will create the issue and pull-request including an update to the documentation

but i would like to know, what is your preferred way to handle the (in this case a lot) duplicate code?
