v23.1.9: More quick fixes and new contents!

*Increased flame sword speed.
*Fixed end game screen not triggering after 30 minutes
*Added repeated bosses after 10 minutes. That's a placeholder while the new bosses are getting done.
*Changed the gold limit. There is no limit now, and the coin purse only increases your gold overtime instead of expanding the gold limit.
*Added exit button on random event screen, so the player can choose to not go to any store and just exit.
*Added item description for all current items in the Gryphon's Goods Shop.
