Adds support for loading UIImage's from PDF files. I think it's a great way to add resolution-independent graphics to your apps, and also remove the "export to bitmap" step from your workflow. Just save directly from Illustrator!

What it does:

- You can pass the name of a PDF file (with or without the '.pdf') to +[UIImage imageNamed:]
- You can use the name of a PDF file inside Interface Builder, in your UIImageView's
- Turn a multi-page PDF into an array of UIImage's... good for animation.

Feedback to gists @nielsbot.com. Thanks!
