"Dr. Robotnik's Ring Racers" rebranding

See merge request KartKrew/Kart!590

- Shortcut waypoints are pink now instead of blue. (barkley's ran into the issue of a shortcut waypoint on the main path too many times)
- Waypoint debug uses a shaded blue sphere sprite instead of a thok sprite, because it makes the color easier to see on different backgrounds.
- Use 1 splat for waypoint radius instead of shittons of orbs

Fixes shortcut pathfinding behavior when the entire shortcut's waypoints have the flag instead of only the entrance.

Wasn't actually being displayed on the window before

Replaced most drrr (mostly only used in system / exe stuff) with the more verbose "ringracers"

More Bot Improvements (Again (Again))

It's really pointless on Flame Shield, and Lightning Shield is boring.

Flame Shield should just get a different passive.

- Rename to Lightning Shield (it keeps fucking me up when I want to kartgiveitem it to myself)
- Fix inflictors causing damage being considered damage hitlag. Fixes the player using Lightning Shield being in damage hitlag state (most notable in the DI branch because hurting someone with it lets you DI afterwards, which also fucks with your turning)
- Rewrote attack function to use custom blockmap search instead of P_NukeEnemies.
- It can no longer attack below you, only above & around you.
- Increased the attack radius, so that it actually lines up with the sprites...
- Fixed extremely inconsistent ring blockmap search by moving it to playerafterthink (don't ask me why)
- Rings get joulsted by Lightning Shield when you pass by them without
- Added MAXRADIUS to the blockmap checks for lightning shield & mines, to reduce blockmap inconsistencies

Pretty much just copy+pasted from Snap the Sentinel!!
- Hold left/right to adjust the momentum angle after hitlag, up to 22.5 degrees. (Only angle can be adjusted, so you can't adjust your speed, only your direction.)
- It's relative to your angle, so sometimes you need to use forward/back, or even diagonals (forward/back throws now store full analog data for this to work)
- Bananas flip DI direction, to make them not baby easy mode
- Tumble has x3 DI (so angle adjustments of 67.5!!), and hitlag on each bounce to allow even more control.

Makes the displayed FPS more accurate to what it's actually displaying.

Also removed HUDTRANS from it -- stop it fading out during level transitions, it's annoying when I actually want to see the FPS during those bits.

Avoids a crash when connecting to a server in the Intro
