Feature Request - Render months as words

I would like an option for rendering the Months as words rather than numbers. 
(Jan, Feb, Mar or January, February, March) I can't see how to plug that into 
the current code easily, without having the lists created at object creation 
time. It seems like it would be a better idea to have the value created at 
render time using a filter function, to allow for internationalization, 
abbreviation, capitalization, etc...

I can do the work, if someone could suggest a good approach.
