Log Message:
Update tor to 0.2.0.14-alpha.
Quite a few crash fixes.
Minor features:
  - If BridgeRelay is set to 1, then the default for
    PublishServerDescriptor is now "bridge" rather than "v2,v3".
  - If the user sets RelayBandwidthRate but doesn't set
    RelayBandwidthBurst, then make them equal rather than erroring out.
