Further refinement to Trick Indicator behaviour

- Set colour in K_DoPogoSpring based on relevant vertical momentum
    - Similar but seperate colour list to Dash Rings
- Improve interp state handling when starting a Trick
- Don't set to S_INVISIBLE every non-tricking frame
- Don't follow the player's movement during the very end of a swipe animation
- Add a catholocism blast of the outer D-Pad ring while tricking
