rendering/game: make player model semi-transparent in ghost form

Browse source 
Add GhostStateCallback to GameHandler, fired when PLAYER_FLAGS_GHOST
transitions on or off in UPDATE_OBJECT / login detection. Add
setInstanceOpacity() to CharacterRenderer to directly set opacity
without disturbing fade-in state. Application wires the callback to
set opacity 0.5 on ghost entry and 1.0 on resurrect.
