demo 2.1 version

I've added a linux version, which is completely untested and I have no idea if or how it works. I have also fixed a couple small bugs for the demo 2.1 version, which is currently only for windows and linux since I have to go through a whole process to make a working mac build. Why, why why why why. 

Changelog:

• Fixed some dialogue that showed the wrong names and portraits
• Probably fixed a problem where the wrong sprites showed during the walk cycle. Idk why this was still there but it should be gone
• I think that's it lol
