    Interpreter constructed its own connection
    
    No, just no. >:(
    
    No clue why Sambuddha did this. Constructing a separate connection is bad for
    several reasons...
    
      1. The interpreter only works if tor is running on the default port. Anything
         else and it's hosed.
    
      2. The stem.connect() prints to stdout and gets passwords from stdin. That
         means nyx is completely hosed in several situations since we're in a
         curses context and that'll freeze or screw up our interface.
    
      3. This second connection is completely pointless. Nyx has a controller
         connection - it's used everywhere. Why did this seem like a good idea?
    
      4. It completely broke our tests if tor isn't presently running on the
         expected port.
    
      5. If tor shuts down and is restarted this won't get the new connection when
         nyx reattaches.
