Update v0.947 fixes and improvements

Update v0.947

Fixed:

• Aspect ratio issue for 16:10
• Universal item reward cost (previously always cost 40 when won in quests or other rewards)
• Boss, beast, or undead quirks are now visible on units immediately, not just when the battle starts
• Replaced all gladiator descriptions at the beginning of the game to simplify and shorten them for easier understanding
