Add support for displayName

[theogravity]

Hi there,

Thanks for react-docgen, it's been really handy so far in being able to document our component props. We have a use case where we want to associate the generated documentation against the component's displayName instead of the filename, and cannot do so without requiring the component in question to obtain it (which can kill build time with more components).

Would like to request that displayName be added to the generated doc, please!

Yes, that should be easy to do. You could write your own handler if you need it quickly, but I'll include it in the next release.

Thank you :D

(Hope you've checked out the react-styleguide-generator issue I have, it has screenshots of what I'm trying to do with react-docgen!)
