Merge pull request #264 from LipuFei/twisted-db

Twisted db
Implement TwistedCallback
Make the tracker use the twisted callback
Twistify the bootstrap and allow it to be disabled
Refactor bootstrap resolution stuff so it works with the new twisted
callback, still some stuff pending to do, but its working just fine.
Port unit tests classes to the new twisted callback
Fix the tests
Community import cleanup
Further twistify the bootstrap process, untested
Skip looping resolution if bootstrap is disabled too
Make callback.call() thread safe.
This means TwistedCallback's contructor can't use it anymore to obtain
the reactor's thread ID hence from now on we need to make sure it always gets
instanced from there.
Forgot to lower the log level for this
convert ip to str
force_dispersy_thread decorator
attempt to fix unregister
add the batch cache timeout callback to the community's pending callback list.
Temporary hack until we fix the shutdown routine
This should fix the race condition with the batch timeout callback
