Removed the aggressive "session_unset()" call in the game's reset function and manually unset each game-related variable by name.
Removed the aggressive "session_unset()" call in the game's reset function and manually unset each game-related variable by name.

The reset function is run when a user first visits the website/game so that the demo mode works, but the complete session unset was causing users to be logged-out of the chat room if they had no visited the website/game *first*.  This patch fixed the problem while still allowing the demo mode to initialize properly.
