Support for plist

[jeyb]

Thoughts on having support for plist?

I find myself rendering plist more than xml for iOS apps and would be interesting in having this capability in rabl. If you're interested, I'll create a pull request. It would work similar to xml rendering but use the cfpropertylist gem.

Interesting, I am all for it, that is why rabl is called the agnostic builder language. Feel free to send a pull. Check out #69 for reference. I intend to pull that in soon too!
