Rework to curses

Here's another small but mighty balance update! This time we received some feedback that some of the curses felt a bit too strong, so turn them down we:

• made all the curses playable to exhaust them
• made almost all the curses get shuffled into the discard instead of deck which should give you a little more time before getting affected by them

We also fixed a small bug where if you quit from the game over screen, it would still say continue game in the main menu

We love feedback though, so if you come up with anything else, just let us know in our Discord!
