Fixed pound signs. Tried to add multiple rounds but ran into some
serious problems. The program doesn't wait for user input before
continuing onto the next player. I'm not sure who coded the buttons, but
could they explain which bit is meant to be doing the waiting? Also the
players can have negative money - I thought this had been fixed. I can
take them out of the player array for further rounds but I don't know if
this will mess anything else up. Comments?
