Lets it stay very long for 1v1 like we want, but not matter the closer it gets to 8 players. Tired of people spamming rings to compensate for this problem :V

Unlockables Undefeatable

Instead, if you want an exception - in the *same* MainCfg block, set `doClearLevels = False` (or `0`, or `No`)

* Prevents the dependency on a `levellist` global that could be corrupted
* Fixes the issue where cups that were not unlocked would not show up on the cup select (because `M_MapLocked` would make `M_CanShowLevelInList` fail).
* Shows both Race and Battle maps in the cup unlock preview.

Invalidate all instances of the same map across multiple cups' `cachedlevels`, so that it DEFINITELY will be assigned to the first cup in the linked list in P_InitMapData.

Don't permit duplicate maps across multiple cups in time attack. A map is only valid for its later groupings in Grand Prix and multiplayer.

* G_GetFirstMapOfGametype now uses the menu functions instead of repeating the effort
* GTR_NOCUPSELECT - allows gametypes to opt out of cup selection

This was carefully adjusted so that Mecha Sonic reaches
199% top speed, barely shy of 200%. Previously, Mecha and
even down to Espio could overcharge a spindash to reach
Tripwire Blaster state.

Also improve math precision by doing multiplication before
division.
