[tor-commits] [arm/master] Replacing TorCtl event listening with Stem



commit c5661eb247da27af7cc6736a1529a7c800150b89
Author: Damian Johnson <atagar@xxxxxxxxxxxxxx>

    Replacing TorCtl event listening with Stem
    
    Dropping the TORCTL_* runlevel events in favor of stem's. I'm also blending
    them with arm's with reguard to selection since stem's largely supplanting the
    logging that arm did.
