Limit options passed from render methods to helper methods

[ericf]

The render() and renderView() methods should not simply pass the options they receive from the caller along to the helper methods they call.

The following doesn't make sense and will break:

app.get('/', function (req, res, next) {
    res.render('home', {
        precompiled: true
    });
});

This will end up calling getPartials() and getTemplate() with options.precompiled = true, and throw an error.
