no Callback after browser:reload is fully complete

[mrt123]

It will be useful to be able to call custom function after browser reload is fully finished. eg:

    devServer.init(...)
    gulp.watch([project.TEMPLATES], {},['compile-templates', function() {
        devServer.reload();
    }]);

    devServer.emitter.on("browser:reload", function () {
        devServer.notify('XXXXX', 20000);
    });

Above will cause notify to be called too early, followed by browser reload, and notification gone.
