Number conversion to string - Menus

[fletchto99]

Hey,

The other week I was hosting hackathon and some users were trying to send numbers as the title of the menu. When they did this the sub-title no longer rendered. I've put together a minimal example to replicate this issue:

var UI = require('ui');

new UI.Menu({
    sections: [{
        items: [{
            title: 89,
            subtitle: 'hello world'
        }, {
            title: 92,
            subtitle: 'hellow world'
        }]
    }]
}).show();

As you can see the title renders fine but the subtitle is not there as expected. The expected output would be:

Thanks for catching this one! Let me know if the fix works for you.
