Refactor of game object

[reddenx]

Game object will no longer have a weapon, instead it will have children which can be weapons of more objects.

Things to think about:

• Should the child be updated via the parent's update, or it's own. If the child is updated via parent, it cannot live in the quad tree, this would mean other things can't interact with the child, the child can only interact with others. Other side would be that they update independently and are in the quad tree, this would have the complications of references from parent to child, resolution of who would get updated first, among other things. I'm leaning towards via parent, for it's simplicity. Either way I can come up with multiple situations down the road that would plague each decision.
• redesign of how objects are represented in the world. Game object will now have an attachment point, and a child attachment point (where it's held and where it holds). These will be represented on a per frame basis. Easiest way I can think of would be to add an origin (where it's held) and an attachmentPoint (where it holds) to the frame. This could be extremely easily implemented into the renderer as one of the overloads takes an origin (there would be some physics tweaking involved).

We should take some time and think this one out.

• [x] GameObject has List Children, children have ref to parent
• [x] GameObject updates its children
• [x] container.UpdateAll modified NOT to update GameObjects that have parents
• [x] Weapon converted to child GameObject. Combine weapon states and actor states. Parent gameobject has state machine that tracks movement, child is weapon that tracks attacks.
• [ ] nice to have: attachment point where it's held (singular), and one or many named Holding attachment points (LHand, RHand, Head, etc). Will both default to gameobject center as they currently do for now.

Watch out if you're writing any code right now. I'm 50% done with the refactor, and there's a lot changing. Nothing we didn't already agree on, it just touches a lot of files.

Refactor done. Sorry, but I did a remove and sort usings on the project and couldn't undo it, making this commit ridiculous.

I want to think about the weapon brains a little more, I think I can get rid of them completely and just have the owner brains fire events... maybe, need to think about it.

I'll just close this since we undid it....
