[yt-dev] Anaconda packages have been updated

The yt conda packages that Continuum Analytics builds for us as part of the anaconda python distribution have just been updated for yt 3.0. Most importantly, there is now a 64 bit Windows build along with the OSX and Linux builds! Right now there are only 64 bit packages, but we should have 32 bit packages soon after fixing an issue that causes test failures on 32 bit builds of yt. If you use conda, you should be able to update yt with "conda update yt". Thanks to Aaron Meurer for helping us out with this yesterday and today.
