[Feature Request] make private flag default

[danii]

Hi, is it possible to a add one or all of the options bellow

• 1. set the private flag enabled by default
  2. detect if the torrent is private and set it on
  3. perhaps allow to change the flag later on

I think this is very useful if you want use DHT and mix free torrents with private ones.

Thanks

1. This is actually going to be included in 0.6.

nice, can't wait for 0.6, keep up the good work
