Add player animation system!

- Hooks into ModelRenderer by wrapping it in an extended version that allows modification of angles after the model has set them
- Is compatible with pretty much everything, yay (even modded armour!)
- Adds property overrides to ItemWand so that gets animated too
- Adds a system for generating override models from a template at runtime so I don't have to duplicate all the wand models
- Tweaks particles and ray spells so they line up with the end of the newly-animated wand
- Fixes a long-standing bug where wand usage actions would stop immediately for all non-continuous spells
