noticed some break changes in the pre-release of the python-transmisionrpc package

[wuliaotc]

transmisionrpc packge（ver:4.0.0a5）changes

1. packge name form transmissionrpc to transmission_rpc
2. Some filed are replaced with property
   • toorrent.isPrivate to is_private
   • trackers['announce'] to announce

I didn't check all the break changes in the rpc package in the pre-release, these adjustments just make him run on my machine.

Might want to check for other break changes once version 4.0 of the rpc package is released.

Thanks for your great work. Just to confirm, are these two fields the only changes that need to be compatible?
