[mpich-announce] move to GitHub

[Kenneth Raffenetti]

Hi folks,

MPICH has moved to GitHub! http://github.com/pmodels/mpich

Come check us out at the new location. We have imported all existing 
tickets from our old bug tracker as GitHub issues. New bugs (and pull 
requests) can be submitted directly to GitHub repo.

The old MPICH git repositories at git.mpich.org are still available, and 
will be kept in sync with the official master branch. This may change in 
the future as we evaluate their utility.

Please contact me if you have any questions at this time. Our developer 
wiki (http://wiki.mpich.org) will be updating over the coming weeks with 
new information, so feel free to point out any mistakes, omissions, etc.

Thanks and enjoy!
Ken
