Changes:

General: continued working on victory conditions.
Globals_Server, Globals_Game, Globals_Client: renamed G_Server to G_Game to clarify that it is to hold game-wide variables.  Moved 2 variables from G_Client to G_Game.  Created new class G_Server to hold variables used across all games.
Globals_Server: created new variables to hold next gameID and collection of victory condition types.
Globals_Game: created new variables to hold start year, duration and victory condition type for that game.
Form1: made necessary changes to Riak read/write methods for above changes.
