In this PR several changes were made:

Enhancements

The "explore" page not autogenerates a list of world links, by looking inside the worlds folder
Magic links now create a link for the creator and allow you to define an arbitrary group name
Object interaction now uses parenting rather than the parent-constraint component for a smoother experience
The circles-artefact component now has been simplified

New components

circles-description component (same as used for circles-artefact
circles-pickup-object (similar to circles-artefact but can now be applied to any object with the artefact's additional features)
circles-pickup-networked [experimental] allows circles-pickup-objects to be networked and shared between multiple users (removes duplicates objects)
circles-lookat allows an object to constantly turn to face another element i.e., the camera (includes a smoothing option)

Fixed some URLS not being allowed in script headers for world
Updated raycasters on circles-interactve-visible so that interactions turn off/on properly
Adjusted [circles-material-extend-fresnel to also work on basic geometry and materials
circles-artefact label and description now append to the circles-artefact's parent, rather than the scene.

Renamed the "hub" world to "Campfire" to be more clear
renamed circles-object-label to circles-label
Added a new "Network_Testing" world to try out synchronized object interactivity
Removed circles-inspect-object (now replaced by circles-pickup-obejct)
Adjusted shadows to be smoother. This needs work
Added some CIRCLES.UTILS options i.e., CIRCLES.UTILS.generateRandomString(numWords)
