Detect server disconnect during character loading and show error

Browse source 
GameHandler::update() now detects when the socket closes mid-session
(e.g. Warden rejection) and transitions to DISCONNECTED state.
Character screen shows a disconnect message instead of hanging on
"Loading characters..." forever. Reverted SHA1(seed+module) fallback
to SHA1(seed) since neither is correct without module execution.
