• Allow opening/closing outside of VR, and allow using right-click in VR instead of hand motions
• Fix open/close bugginess (maybe we need to open/close client-side too?)

This issue finally made me have to use mixins, since Minecraft looks at people who have the chest container open to see if it should close a chest or not. Since immersives aren't containers, I need to track these counts separately, and use a mixin to hijack the return function to include these counts.
