Don't output warnings in quiet mode

For sake of simplicity, and also to distinguish warnings from errors.
So now we have:
  * errors: output to stderr, are **not** silenced with `-q`
  * warnings: output to stderr, are silenced with `-q`
  * info: output to stdout, are silenced with `-q`
  * solicited output (like help, info, or list): output to stdout, does
    not make sense to be silenced with `-q`

We also only have warning in 3 situations so far...  :- )

+- Be quieter and don't output warnings when `-q` is provided.

 ### Fixed
 - Error in `zimfw update` with the `git` tool when module directory is under a
