Changes included:

Security updated to disallow multiple moves. Otherwise it was possible for a player to copy the game file (*.ksg) and then make a move to see what happens and then restore the game and try another move and thus gain unfair knowledge.

While at it, added a feature to keep a record of the current game being played. When starting KRef, it is now not necessary to go down the menu to find the game, but just press "=". Already one could exit by pressing ESC rather than going down the menu to select option "Quit". As the menu is not mouse driven, it is annoying to use. Now just "=" and ESC are all you need except when first establishing the game to be played.

I noticed that if the "=" feature was used after the game itself had been deleted, it correctly said "Game File Disappeared" but created a zero length game which was annoying. Fixed that to erase the zero length game.

Patch to display to reverse row numbers in final display (see DM3BB-Display)
