release/0.2

Fix initial push syntax in README. Needs to say "refs/heads/".

Clean up more files in debian/rules.

Mark the generated egg as non-zip-safe.

Ensure "git init" doesn't write to stdout, and confuse a push.
The repository autocreation functionality ends up sending the
stdout to the client side, and there a very confused git push
can't make any sense of the protocol.

Adjust README to make adduser create the home directory.

Avoid missing configuration file trouble on initial run
of gitosis-init (and hence, gitosis-run-hook).

Allow using email address in SSH public key user fields.

Make sure ~git/.ssh exists in gitosis-init.
