Add option to use Rupees as ammo

[CharadeNut]

This is inspired by ALttP Randomizer's Retro game option, where the player uses rupees instead of arrows. With this option, the player will use ammunition as normal, but once the ammo count is about to reach 0, rupees will be spent to bring it back to 1. This applies to the bow and slingshot, but also bombs, bombchu, sticks, nuts and magic (magic's threshold is the cost to use Nayru's Love, to make sure every spell can be used with rupees). Rupee costs are as follow: • Bow: 4 rupees • Slingshot: 2 rupees • Bombs: 8 rupees • Bombchu: 12 rupees • Deku Nuts: 4 rupees • Deku Stick: 15 rupees • Magic: ~24 rupees to use Nayru's Love, 1 rupee for a charged spin attack
