Beta v2.1 - Added Boss Sprites

A simple quick fix to add the sprites for the boss, as I forgot to add them in this build, along with Tonto's sprites.

Additions:

- Sprites for the boss of the demo.

- Sprites for Tonto.

Things to add:

- Add overworld walking sprites for all characters, currently only the main character has walking sprites.

- More side quests.

- Add the rest of the art.

- The rest of the game.
