[Swift-devel] making this list no longer require subscription approval

[Ben Clifford]

This list has traditionally required subscription approval; I'd like to 
make it so that admins do not have to approve people for subscription any 
more - it takes time and I don't see that there is any value gained by 
this. So I'm going to remove the requirement from the config for this 
list - subscriptions will then act like swift-user subscriptions do now.
