This reverts commit 2cf94ea6.

Edit config to account for new behaviour (plus add gold mode for the Eggman Statue, which I forgot to add earlier).

Updated the list of which skies are associated with which maps, rearranged the list of character to match the character select in-game, and added myself to the file's credits.

(Re-did all of this because I think I messed up the branches and stuff last time.

* When activated, stops the timer in SP/MP.
* Applies to the mapheader countdowntimer as well.
* If you're playing Record Attack, also exits the level immediately.
* It has no special modes, no linedef flags, no parameters, nothing.
* Only not an innate property of A_BossDeath because people may want it to NOT happen sometimes, or make it happen with non-boss events too.

Also, skip over calling P_DoPlayerExit if the player isn't in game.

Make spinbust behavior consistent with other bustable blocks and rename FF_ONLYKNUX to FF_STRONGBUST

* Make the Amy Cameo only spawn in SP, Record Attack, or Co-op unless it's the Clone Mode.
* Add the diagonal spring flag options Red and Yellow Diagonal Springs have to the Blue Diagonal Spring as well.
* Put diagonal blue spring in config.

    * Red and yellow Boost panels!
        * Added because SUBARASHII and KIMOKAWAIII had several levels using them, and I wanted to make them look better.

        * Uses the mapthingnums of Glaber's SOC resource boosters, but absolutely nothing else - not even the magnitudes.
        * Apply MF_AMBUSH to force the player into a spin - even if they don't have a spin ability!
    * Banpyura!
        * A Crushstacean with a spring instead of a crushclaw.

        * Wanted this for a while, finally added it.
* Improved springs.
    * Add pw_noautobrake to disable autobrake for half a second when touching yellow horizontal springs, and a second when touching red ones, even on the ground.
    * Add pw_justsprung to disable directionchar for a few tics while touching any springs with a horizontal component to their velocity.
    * Add the diagonal spring flag options Red and Yellow Diagonal Springs have to the Blue Diagonal Spring as well.
    * Started but decided against a tip of the hat to the CD spring spin, hidden behind #define SPRINGSPIN.
* Make directionchar "lag behind" a little bit in waterslides.
* Improved flame jets.
    * They now use new sprites for having their flames move upwards and sideways, instead of having them always face downwards like in 2.1!
* Fixed a mixed declaration and code error in A_RolloutRock. (Sorry Lach!)
* Make the Amy Cameo only spawn in SP, Record Attack, or Co-op unless it's the Clone Mode.
* Improved ZB config.
    * Add above new types.
    * Add Blue Diagonal Spring, which existed in the source but not the config.
    * Re-order enemies in ZB config by zone (but keep them in the Enemies section only).
