Some small bug fixes and QoL changes

• Fixed an issue with the quit button so you can actually stop playing the game (it would seem my attempt at world domination failed)
• Button hover transitions should now no longer stop working
• Enabling and then disabling the dyslexia-friendly font will no longer change the font next to the tick box
• When you're hovering over a space where you can place a piece, you will now see a "phantom" piece there
