Updated help output to prefer true/false to yes/no

Similarly, I updated the API Reference too:
https://github.com/ariya/phantomjs/wiki/API-Reference/7cddd19676a917535b74d386c3974da00fbbe793

This arguably makes more sense to PhantomJS's typical audience of web developers.

Make require.stub() optionally accept a factory function

require.stub() can now accept a factory function instead of an object
so that stubbed modules are initialized lazily:

require.stub('zlib', function() {
    // initialized once, when zlib first required
    return {
        createGzip: function() { ... }
    };
});

available).
