[Config] Support extension for Podfile.

[fabiopelosin]

Add extension to the podfile so it can be associated to an UTI in the Mac OS X Launch Services.

Feel free to add it :)

What is the reason for doing file extension? As example, Gemfile is without extension, and survives )

@xslim To my knowledge in Mac OS X you can't associate an application to a file based on the name, you need the extension or you can associate with public.data and *. I wan't to be able to associate all the Podfiles with a dedicated CocoaPods application (https://github.com/irrationalfab/Ikeda).

I’m not yet sure about the scheme, maybe it should be .podfile so it’s more like .podspec, but for now it’s good enough so that you can use it in Ikeda.

What about Dependencies.podfile ?
