[non] nsm api documentation, ladish

[rosea.grammostola]

Wouldn't it be wise to remove Ladish from the API documentation? To 
avoid future confusion and having to deal with different session 
managers? Afaik Ladish is a project of the past.

"The value of name_of_session_manager will depend on the implementation 
of the NSM server. It might say "Non Session Manager", or it might say 
"LADISH". This is for display to the user."
