Adapt a patch from goodell to let the contrib/exitlist script

Changes in version 0.1.2.7-alpha - 2007-??-??

 o Minor features:

    - Check for addresses with invalid characters at the exit as well as at

      the client, and warn less verbosely when they fail.  You can override

      this by setting ServerDNSAllowNonRFC953Addresses to 1.

    - Adapt a patch from goodell to let the contrib/exitlist script

      take arguments rather than require direct editing.

 o Major bugfixes:

    - Fix a crash bug in the presence of DNS hijacking  (reported by Andrew

 example usage (Tor 0.1.0.x and earlier):

    python exitlist < ~/.tor/cached-directory

    python exitlist 18.244.0.188:80 < ~/.tor/cached-directory

 example usage (Tor 0.1.1.10-alpha and later):

    cat ~/.tor/cached-routers* | python exitlist

    cat ~/.tor/cached-routers* | python exitlist 18.244.0.188:80

 If you're using Tor 0.1.1.18-rc or later, you should look at

 the "FetchUselessDescriptors" config option in the man page.
