It's just... TOO good, despite the couple of issues with it

(please don't spread these fixes out across different branches :boi:)

# Conflicts:
#	src/k_kart.c

- Renamed Grey to Nickel, and Cloudy to Grey
- Updated Silver and Nickel to look a teeensy bit more inbetween White/Grey and Grey/Black, previously they both leaned more toward Grey
- Drastically changed Navy to be more distinct from Jet
- Replaced Indigo with Pomegranate
- Moved certain colors around to match (most notably, beiges and browns are in their own little sub-section after the greyscale colors, instead of being lumped in the middle of orange and yellow)
- Updated color opposite table to match

Squares the colors to get nicer looking results (https://www.youtube.com/watch?v=LKnqECcg6Gw), as well as only blending a small chunk of the skincolor to prevent desaturation from the brightest/darkest values.

Gets more accurate looking results

Leaving behind a commented out define for now because I dunno if I like it yet

(I mean. I still think this feels nicer than pressing the menu button, but...)

Try to make all the blues using this range look a little different, you know?
- Cyan is brighter, and has more contrast.
- Teal has 1 more shade of blue for slightly better anti-aliasing.

- Renamed Ivory to White, removed Nickel and old White, and improved Silver and Grey.
- Improved Pink & Ruby.
- Added Ketchup, replaced Canary with Mustard.
- Removed Army.

More manual pages, plus renaming the option to `Tricks & Secrets (F1)` - PLUS, the magic of a little animated how-to for leafing through the pages. Requires new patch.kart, as I wanted the leading zeroes and Jeck wanted to add more pages without more commits later...

No other keys bound to this, it should be 0

Should make Hyudoro even more amazing in Battle, since you can tell which held items are off-limits~

(In return for not letting anyone experience this silly bug, I made spectators joining before the match starts in Battle spawn with bumpers)

- Keep items on death, as long as you haven't used them yet.
- Restart the item roulette on spawn if you die during it.
- Held items that take up your item box now flash, to be consistent with Rocket Sneaker and Grow.

- Fixed camera panning for higher distances.
- Because of this, re-enabled scaling the pan amount based on distance.

New respawn boost behavior, where you just hold for long enough instead of timing it with hitting the ground. Also much weaker, just gives you enough boost to get going instead of being a free sneaker.

Start boosts have been severely changed. The perfect one has an extra tic on its timing window and gets Sneaker boosting special effects, but every other possible boost has been severely nerfed.

Based on input recieved from Jeck
