Patched jtorctl to pass more information about circuit events to the
controller to help us debug connection problems.

This may have been the cause of bug #69. Removed the wait-for-shutdown
code in DroidtoothPlugin that was added to attempt to avoid that bug.

Thanks to the team that audited CryptoCat for this idea. :-)

This may have been the cause of Bluetooth not always being disabled at
shutdown on the Sony Xperia Tipo.
