Demo update v0.82

Small update for the demo to add in hotkeys for equippable items and a small adjusted to ammo balance (got a few complaints of the game being a little too easy after the last update). Keep in mind that balancing is still a work in progress. [h2]Changes:[/h2] -Equippable items can now be assigned to number hotkeys. -Number keys now cannot be used when rebinding in the controls option menu. -Reduced Ammo amount when picking up shotgun ammo to 2 (Was 3). -Added shotgun and pistol ammo pickups to Servant Dining room (room with the shotgun). -Added hidden shotgun ammo pickup to courtyard (area with the dogs). -Some fixes to dialogue.
