Currently this breaks some parts of the ACS functionality ... before I made a handful of small extensions to ACSVM's slightly-limited C API myself, and I didn't get them into the actual repo yet.

But now that we've moved to actual C++ compiling, I will likely just flat-out rewrite the SRB2 side of the code in C++ so it can use the library directly.

Add TESTERS and HOSTTESTERS builds to CMake options

See merge request KartKrew/Kart!830

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

P_LoadLevel calls some functions that save gamedata and
unset save_p.

Closes #350 and #324

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.

Fix not being able to play sounds from sector->soundorg

See merge request KartKrew/Kart!828

- Things with MF_NOCLIP can still run code when touching things, but won't be blocked by them.
- Things need both (MF_NOCLIP|MF_NOCLIPTHING) to do a single movement step, since MF_NOCLIP can do thing collision now.
