[data-carpentry-discuss] Splitting up main Data Carpentry repository complete

[Ethan White]

With the closing of [#117] I am happy to report that our efforts to 
split up the main `datacarpentry` repository and recover the history 
that had been lost during initial efforts are now complete.

Following Software Carpentry's lead this will make it easier to maintain 
lessons and allow folks to focus on getting notifications only for 
lessons they are interested in actively watching.

This also means that the old `datacarpentry` repository is now inactive. 
It will be maintained for historical purposes, but any new changes 
should go into the repositories for the individual lessons that reside 
in the Data Carpentry GitHub organization.

Thanks for all of your patience during the reorganization.

Best,
Ethan
