[PERFORMANCE] Implement Dynamic Storyboard Building

[menvae]

This pr was detached from:

• [PERFORMANCE] General Optimizations #264

The storyboard is now guaranteed to be NIHAHAHA and so so sogoi omg wow

Changes

• We now keep track of all storyboard elements allowing us to only update what we need, this means too that we don't need idle tracker for normal non-script generated elements as it now updates instantly
• Loading icon now is shown/hidden depending on whether a region is loaded
• Storyboard Animation now has a ParentElement field which allows us to actually rebuild specific elements when animations are updated
• each script's drawables are now put in a dedicated Compound. this is for ease of use. There could probably be a better way but this works.
