Default Git branch should now be called 'main' not 'master'

[noud]

hi,

given the whole #BLM movement all on GitHub is now prefered to name the most master Git branch not 'master' anymore, given the connotation it might arise, but 'main'.

This defaulting to another Git branch, the branch 'main' is default since 3 weeks or roughly a month in whole GitHub. So i raised a ticket no about adding a Git branch 'main'.

thanks,
noud
