07-23-2012:  Added karooctl commands for listing rtp proxy and registrations.

07-23-2012:  Added facility to store RTP state to redis.

07-20-2012:  Added flexi-route validator via karooctl.  Bootstrap script now
  validates flexi-route prior to starting Karoo Bridge.

07-12-2012:  Added new config parameter to disable the internal FreeSWITCH
  trunking.  We also changed the bind address for ESL from default IP
  to localhost.  There is no need for this to be exposed to the public.

07-10-2012:  Improved Sahara to use /proc/ for process management instead of
  spawning ps aux which consumes a lot of CPU.

07-03-2012:  Introduced karooctl command line utility.  This will serve as the
 central utility to control and configure Karoo.

06-14-2012: Exposed resolved target-address and target-host parameters to
  outbound.js callbacks.  This gives the Flexi-Route layer do more actions
  to the SIPMessage prior to hitting the transport layer based on target-address
  and target-host.  target-host contains the domain or IP address while
  target-address always contains the resolved IP address.

06-09-2012: Added msgResetMaxForwards to Flexi-Route.  This function allows
  rewriting of max-forwards header which might be too low a value to properly
  allow SIP Messages to spiral in systems like sipXecs.

06-03-2012: Added RTP packet resizing capability callable
  by setting rtp-resizer-samples Sip Message property  in route.js.  The resizer
  buffers g.729 and g.723 rtp to a higher sampling rate.  60 - 120 milliseconds
  is known to be an acceptable value for resizing RTP.

06-01-2012: Karoo Bridge 1.5.0 released.
