Animate Scene Swapping

[lishaduck]

Description

This PR refactors how we swap scenes to use signals.

Note: Testing this lead to some non-reproducible bugs. If someone could look into it, that would be really nice Note2: This'll also refactor global state and the HUD, but I haven't done that yet. CC: @MattsAttack
