torsocks 2.0 compatibility

hi, torsocks 1.3 or whatever has been superseded by 2.0 - the configuration file syntax changed, and it doesn't support regular SOCKS anymore, but only tor. so no need for the protocol bit.

thanks for this, i love the simplicity
It would be nice if the script detected that and warned about it.

Also, this comment says "torsocks 2.0 does not allow connections to `127.0.0.1`" but doesn't explain how that's related to the rest of the sentence. I suggest changing it to:

If you already use torify connections to keyservers with `gpg`'s `http-proxy` keyserver-option in your `gpg.conf`, you will need to pass `http-proxy=` here to disable it. `parcimonie.sh` needs to run `gpg` with `torsocks` in order to ensure that all key grabs happen on different Tor circuits, and torsocks won't allow `gpg` to connect to its `http-proxy` on `127.0.0.1`.
