* Instead of doing constant G_MapNumbers when finding the relationship between maps and cups...
* Add a cache of level IDs to cups, to go with the strings.
* Add a cache of the cup pointer to maps, so we don't have to search through all cups to find our map. (done in P_InitMapData)
* Pre-emptive work: G_IsSpecialStage and P_GetNextEmerald now reference cup data instead of a hardcoded ID set.
* Remove a bunch of old stuff from mapheaderinfo_t/associated, and reorder what stays
* Countdowntimer? 💥
* Startrings? 💥
* sstimer/ssspheres? 💥
* forcecharacter? 💥 (distinct from forceskin)
* interscreen? 💥
* sstage_start/end and smpstage_start/end? 💥💥💥💥
* You've been blocked
* G_MapNumber now returns a special NEXTMAP_INVALID if not found, for more consistent reference.
* Incorporate a good chunk of the `edit-headers` branch. Can't clear maps individually because of the new restrictions on sequential mapheaders, but we can add a "disable in vote screen, not even for map hell/archive" flag to a map at some future juncture for equivalent functionality...
Also:
- improved error prints for SOC condition definitions
- improved bounds checking to use `nummapheaders` for iterating over mapheaderinfo
There are still situations that use NUMMAPS like mapvisited, randmapbuffer, etc, which need to be addressed before merger.

- Tangible - collision activating objects, minus rings
- All - every object
- Intangible - the opposite of Tangible, also no rings
- Rings - rings
- Make the menu-only dummykartspeed and dummygpdifficulty cvars also affected by the unlock system.
- Master mode is currently behind SECRET_HARDSPEED, this can be changed later when we're seriously thinking about unlock progression.
- Complete forwardport of changes to cv_kartspeed from 1.4+, since I missed a spot previously.
Overwriting the global power level all the time and not updating any code to use the profile was extremely yikes. This also allows for splitscreen players with power levels.
