Add singleSession attribute to @SendToUser

Browse Source 
Added the ability to send a message only to one user session. Given a
user has two tabs open and the client sends a message to the server
from tab 1, it is now possible to send a reply message to only 1 tab
instead of the default mode of targetting all known user sessions.
