[Open Assets] Jaituia's Factory v5.0

- Added one new character : Demon Core. Faster than regular characters, but instadeath when bumping anything (it's definitely a joke character).
- I've made some changes on how characters are packed. Now there are 4 different packs depending on which characters you want to download :
> The Normal Pack contains only standard characters.
> The Special Pack contains only lua characters.
> The Complete Pack contains all characters.
> The Individuals zip contains each character separately.

- Added one new character : Akuii. As a bonus character, Akuii comes with a gameplay gimmick. His weight scales on how many rings he has.
- Small sprites changes for Bahamut.

Added one new character : Bahamut.

This is now a character pack, Dragon is not alone anymore !

Added two new characters : Tofu and Lysander.

Dragon and Tofu are packed together, Lysander is only available as an individual file.
