Removing Touchscreen Handler

Yes, it's probably an oversight really. In the browser you've got window, and we should really have something similar. The 'root' is of type Hardware, so really we should have a hardware variable that can be accessed.

However, you can create a global variable just like:

function foo() {
  global = "Hello";
  var local = "World";
}

It works even for objects too - so you've actually got to be careful about using var in functions of you end up creating a lot of global stuff :)
