New features for improved memory usage

Thanks for this explanation -- it was VERY helpful :)

So I basically managed to reduce my entire code to:

console.log("hello");

and it was still the same error. Your suggestion of looking at the logs was good and I may have found the problem. Basically it appears at one point to look for an ESP8266_4MB.json at the http://www.espruino.com/json/ ,but there isn't one there, as it would appear that its not been updated (ie: there's a board in GitHub for this board, but not in the /json directory online).

Could this be it? I can't get my code much smaller than one console log :P And yes I did reflash the board each time before I did this, to make sure I started from virgin state on the board.

If this is true though it raises another issue. The IDE will freak out with ANY custom board that you make (I have a couple with different JSVars and stuff). Can I put these in a local directory, and where would be the best place?

Thanks again :)
