Membership requests to Docs FAS Group

> I think that keeping things away from being (almost) instantly accessible makes sure fresh contributors are sane. I wouldn't like someone to go rowdy-dowdy over the documents that my team members have spent their time and efforts on. Translation is a rich ground for argument anyway.

Thats why the commit group is invite only, anyone can join docs, but
in order to go messing with git repos you have to be a another group.
That group is invite only because only people who have shown to be
trust worthy should be able to push, others can pull and submit
patches.
