Quick Bug Fixes

Really appreciate all the feedback I didn't expect to get this many people trying it out so fast. Here's a quick list of what I fixed.

• Can now update your bet if you have more bet than cash so you don't get stuck.
• Added an x to the dialogue to make it clearer it closes.
• Adjusted the game over logic so you only get a game over at the end of the round if you are still at 0 cash.
• Added a small wait before the game over screen appears.
• Removed the "Sure!" and "Nope!" message from changing bets.
