Mac Support and Crafting System

I didn't think I would be able to release this build today because the crafting system was giving me trouble, but here we are! Here's some stuff that's changed:

- Added Mac Support. 

- Added a crafting system for character tasks (SUPER SUPER ALPHA)

- Changed Aki's task and gave Aia her own task. (I have plans for all tasks, but implementation has been slow.)

- Created concepts for new characters (not in the game yet)

We're almost done with the demo, I can sense it! Next build will have tasks for Kei and Daiki.
