Extending modernizr core tests without changing the core

gistfile1.js

if(Modernizr.postmessage) {
    // So we can extend it but still do `if(Modernizr.postmessage)`
    Modernizr.postmessage = new Boolean(true);

    Modernizr.postmessage.extend = function() {
        // Do some tests
        return bool;
    }
}

Well there you go, more thinking of external peeps extending core methods through plugins. Like all the legacy stuff should be plugins flexbox, gradients etc.

Yeah.

I think that makes a lot of sense.
