Online minification mangling code

Oh, great. Thanks for letting me know.

Just so others know... If you choose Closure (online) - Simple Optimisations for the normal Minification settings,

setTimeout(function(e) {
  console.log("Hello World");
}, 100);

Gets converted to:

setTimeout((a)=>{console.log("Hello World")},100);

Which is an Ecmascript 6 feature to allow you to write even more incomprehensible JavaScript code.

I'd turned on ES6 support in the Web IDE's compiler so that we could properly minify binary literals, but it looks like they've added some ways to cut down the number of characters even further now by using some other bits of ES6. I'll see what I can do to fix it.
