Handle invalid number of arguments

See merge request !37

When a remote user with a valid SSH key runs something like 'ssh
git@gitlab.example.com foobar', gitlab-shell would raise an exception in
the GitlabShell#escape_path method. With this change, we catch an
invalid number of arguments as soon as possible and exit.

Update README Markdown style to match CONTRIBUTING

Use simplecov for development.

GitlabUpdate: use stripped path for repo_name

Improve coverage.

Use a default for gitlab_url that usually works

This default lets gitlab-shell connect to Unicorn directly, instead of
going through Nginx. This has the following benefits:

- the majority of users no longer has to edit the `gitlab_url`;
- avoid issues when the external GitLab web address does not resolve on
  the GitLab server itself;
- avoid SSL certificate issues.
