Parse SMSG_GAMETIME_SET/UPDATE/GAMESPEED_SET for sky clock accuracy

Browse source 
Server sends periodic game time corrections via SMSG_GAMETIME_SET and
SMSG_GAMETIME_UPDATE (uint32 gameTimePacked). SMSG_GAMESPEED_SET also
sends an updated timeSpeed float. Applying these keeps gameTime_/timeSpeed_
in sync with the server, preventing day/night drift in the sky renderer
over long play sessions.
