Load configuration and create build directory for bare repositories

"Pretty printing" `config.yml` in order to make it editable by humans. `5` is just value which is looking good for me. It produces a `config.yml` like this:

    prevstage:
        - start
        - database
        - github
        - email
    b8:
        database:
            servers:
                read:
                    - localhost
                write:
                    - localhost
            name: phpci
            username: *****
            password: *****
    phpci:
        url: 'http://phpci.my.org'
        github:
            id: ''
            secret: ''
        email_settings:
            smtp_address: ''
            smtp_port: ''
            smtp_encryption: on
            smtp_username: ''
            smtp_password: ''
            from_address: ''
            default_mailto_address: ''

I guess the `prevstage` node can be replaced before writing? If yes I'll prepare that.
fixed counting of errors and warnings in Plugin/PhpCodeSniffer;
use --report=emacs in Plugin/PhpCodeSniffer to not spam the logs with the full blown report but rather display a small human readable summary report
fix Plugin\PhpParallelLint to reflect latest upstream changes:
> executable is now "parallel-lint" instead of "run"
> supports --exclude flag (ignore directories)
store errors from parallel-lint as build_meta (key "phplint-errors");
