Integrate directly with Keybase

[rsyring]

I'd like to see this integrated directly with keybase. Right now, I have to:

1. Follow someone on keybase
2. Import their key into gpg
3. Sign their key in gpg
4. gitcrypt add-gpg-user ...

I'd like to propose additional functionality that would permit:

1. Follow someone on keybase
2. gitcrypt add-keybase-user ...

With keybase now providing both personal and team repositories I would question whether this FR is still relevant ? I am using both for my repos in a 'belt and braces' type setup fwiw and would welcome this functionality

Keybase's team repositories don't really help with a case where I've got a project on GitHub where I'd like to encrypt a single file, right? Unless there's a workflow I'm not familiar with.

Why not just fully rely on keybase instead?
E.g. keybase encrypt --team foo -i secrets.yml -o secrets.yml.keybase.

This would help a lot. Yes please.
