Function.prototype.bind undefined for command line / phantomjs about jasmine-rails

[searls]

This is something I had no awareness of. PR's welcome!

I have a few dependencies that rely on function.bind and this prevents me from running my tests on the command line / ci service.
Ariya has made it clear they aren't going to patch this (https://groups.google.com/forum/#!msg/phantomjs/r0hPOmnCUpc/uxusqsl2LNoJ). Supposedly it won't be an issue for 2.0.
In the meantime it would be nice if we could include a simple polyfill like the one below.

/**
 * Function.bind Polyfill for ECMAScript 5 Support
 * Kangax's bind with Broofa's arg optimization.

 */
if (typeof Function.prototype.bind !== "function") {
    Function.prototype.bind = function() {
        var slice = Array.prototype.slice;
        return function(context) {
            var fn = this,
                args = slice.call(arguments, 1);
            if (args.length) {
                return function() {
                    return arguments.length
                        ? fn.apply(context, args.concat(slice.call(arguments)))
                        : fn.apply(context, args);
                };
            }
            return function() {
                return arguments.length
                    ? fn.apply(context, arguments)
                    : fn.call(context);
            };
        };
    };
}
