[hyperkitty-devel] Move to Git and Github

Hi devs, You probably already heard of it, we're switching to Git as a VCS, and moving the sources to Github. The wiki and ticketing system stay on fedorahosted.org. The main reason is our familiarity with Git vs Bazaar. The new address is : https://github.com/hyperkitty. Just ask to be added to the committers group if you want to. I've update the wiki page. Cheers ! Aurélien
