Remove the multi-file ZB configs. We're stick with the single-file config for ZB and doing all the UDMF stuff in UDB

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).
