    Add reconnect() controller method
    
    While working on Nyx realized we need our connect() method to reconnect *and*
    authenticate. Without that multi-threaded access can do the following...
    
      CONNECT
      GETINFO stuff
      AUTHENTICATE
    
    That intermediate GETINFO causes tor to disconnect, failing our attempt to
    authenticate. We can't do this in our connect() method (since that's already
    part of our BaseController) so adding a new reconnect() method that does both.
