DOC/RLS: remove duplicate content in release.rst and move remaining to whatsnew
Related to discussion on mailing list https://mail.python.org/pipermail/pandas-dev/2014-May/000272.html

So I gave it a try, moved all content of release.rst to the whatsnew file (main chunk were the bug fixes, and for the rest some api changes and enhancements that were not listed in whatsnew). All content that was in release is not in whatsnew.

Can you see what you think of this? 

looks great!

also, can you build the final docs and either e-mail or put them on the server?

(can always rebuild them if any issues). But I need them to provide links for the announcement doc.

thanks
 @jorisvandenbossche actually don't need the docs built for the ANN. let's get this in and I'll take a look at the built docs final time today.
 I pushed some small fixes. Rest of the docs are building fine, I will send you later this evening or tomorrow
 gr8 thanks!
