Using a property called "settings" in the data passed to a view/template breaks the lib

[Tommaso Sotte]

Using a property called "settings" in the data passed to a view/template breaks the app.
As far as I've investigated the settings property is used by hbs.js in the middleware function.
If the data passed to the render function of view.js contains alreayd a property settings is doesn't get used correctly, and some information is missing, particularly the view directories (view_dirs in hbs.js).

I'm using hbs as a template engine for expressjs. It all starts as a call for res.render():

...
res.render('settings', { settings: {...} });
...
