Full content in user feeds and somewhat smarter titles

I'm a C->Python->Ruby developer and always feel like I'm hacking good code into horribly ugly PHP trash when I try anything in JavaScript, but I wanted to try to help build this out because I actually need it.

What I've done is focus on getting full content of the feed object into the ```<description>``` tag. Ideally, this would probably be best as ```<content:embedded>``` but I'm not sure how to do that cleanly.

All the code is _super_ explicit, so rather than build out ```jsdom.document``` in a smart way, it's all HTML strings (hence it looking like terrifying PHP). I can DRY this all up, but wasn't sure what your goals were for content embeds.

Also, videos don't work, don't have time to figure that out yet.
