Updated script to goldencow2's 18Engine.

Updated bug fixes reported by Dr Zoid PhD - thanks!

--Fixed bug where saved games, upon loading, would reset all counters and treasuries to zero.

--Added individual player and company transfer buttons for easier cash transactions to the bank.

--Altered functionality for treasuries. Player/railroad treasury counter buttons are disabled. Use the transfer board for all money transfers.
--Bank reserve automatically rolls down every available dollar
--Anchored bank scriptable zone to move as the board moves

--Altered asset logs to omit companies with zero holdings
--Tidied up the game space
--Imported blank background images for button boards
--Added a wood colored side for the stock value tokens. Flip the stock value token over to indicate that railroad has acted in the current operating round.

--Added new game button
--Bank reserve automatically shifts down to the main bank when the main bank is below 3000. 3000 will also shift back up if the main bank is over 6000 (because the counters are limited to 4 digits).
--Private companies now payout to railroads. As long as the private company is on the railroad's charter, the private company will only pay to the railroad.
--Added chat outputs for dividend and private company payouts.
--Added an asset log to verify that shares are properly within each player's scripted zone.
--Centered the player counters and asset logs on the scripted zones.
--Added back buttons for the pay from and pay to buttons.
