network, web_service: Add Verification backend and use new lobby API
Added verify_backend to load user_data for members. and removed method to generate UID as this is now done server-side. Added GetUsername function and a "token" param to room_member. Also added a username to ChatEntry, so that the username can be shown (along with nicknames) in the chat dialog.master
