Public Demo 1 v3 Checklist Update

Hi!

I decided to give one last minute update before releasing this first Godot demo (hopefully today).

Here's the updated checklist that I worked on this past week. There's multiple new features ported and improvements but I had to cut few elements from this original list.

Only things that were missing are few AI things and Ammo system.

The AI is having bunch updates (especially animations) before the Public Demo 2, so I didn't want to spend time on soon to be obsolete work like implementing placeholder death animations. Also the behavior things such as Evade and Hunt need first a little bit investigating since there's one bug related to pathfinding that need's to be fixed first.

In terms of Ammo system, I decided to implement Medical system instead for this first Godot demo. I will be making some small changes to that ammo system, so I didn't want to bring that exact Unity one to Godot.
