Add support for "execute and detach" semantics. This allows the FFI to "fork" code to run on the server and tells the gem to keep running if the client logs out and/or closes the socket.
Add GsSession>>logoutNbNoError method to call GciTsNbLogout(). This method causes an immediate logout without waiting for a response from the gem.
This was a bug. GsSession>>logout now raises an error if the session is not logged in. To avoid the exception, use #logoutNbNoError or #logoutNoError.
Remove whitespace from stone, netldi, host, logPattern, dirPattern .
