[Borges-users] StateHolder II

[Слепнев Владимир]

Also, I don't understand why we have to access current_session from 
the constructor of StateHolder. Obviously, every StateHolder instance 
is associated with some session; why not make this association 
explicit, maybe by adding a Session#state_holder(contents) method. 
This would be more intuitive for the app developer too. I could do 
that, if you agree.
