Add Cutscene system

[LinkofOrigin]

The Tutorial has some rough pacing since the player has control at all times. Plus, may objectives or changes to the world are unclear as stuff just sort of appears and disappears when objectives update. A cutscene system would help with both of these so break up the flow and visually show the changes to the world.

The cutscene system doesn't need to be robust. These would be enough to have a big impact:

• Move camera to match a transform (position, rotation)
• Move camera back to player
• Add letterboxes to the top and bottom of the screen during the cutscene
• Hide UI/HUD during the cutscene
• Disable the ability for the player to control the character or open UI screens like the inventory
