General
Events now bind to custom event emmiter (levelEvents) rather than the scene, this resolves issues after scene restart.
Boxes
Changed the way checks are done. Now using sceneUpdate to process box handling and rendering when carried.
Added getRelatives to box and using that to update other boxes. This resolves an issue where you couldn't pick up a box that was previously under another
Stopped unbinding sceneUpdate when a box destructs else you could no longer pick up boxes
Utils.js utils
getBodiesAround now takes typeString to filter returned bodies
Added closestOfType which finds the closest object of typeString
Added getFirst to AroundGrid
Refactor
Moved utils from index.js to Utils.js
Hud now uses scene.registry rather than updateHUD
