Author email and link should be optional

I do not wish to provide email address in the feeds but the code breaks if I just omit it.

@brickcap Fixed in 3267097

Not yet updated on npm thought, so you can commit the repo or just update your ./lib/feed.js file. Thanks!

@jpmonette Can you please update the npm as well. In my application I am using feed as a dependency in package.json. So the users of my applications have to install these dependencies locally. It is not possible to manually update the libraries for every user.

@brickcap Should be good now. (btw: your project looks really interesting, I'll watch it and maybe use it :) )

Please do :) feed has been really helpful for me. I would have spent days otherwise trying to implement various syndication facilities. It is a wonderful library.
