- git-send-email was implemented for a future RPC service for SMTP that
was never created and can have some risks. As dev has no networking by
default and the service was never created, removing it;
- git and gnupg already present in the included states;
- remove commented code; and
- move separate salt state to default installation as it only contains a
single package that is not troublesome.
Document qusal.ConnectTCP in dev's Access Control as it defaults to deny
and causes confusion to users why it doesn't work by default. This is
an exception of the rule that a formula cannot document the RPC service
of another formula to avoid duplication.
