[469c] Engine use StandingCount without init it

[SeriousBuggie]

Map can come with set StandingCount on actors and movers. This can destroy internal engine logic.

Suggested set this value to proper value. Possible it be just zero, or maybe need iterate over all actors, find how many based on this actor and set StandingCount to this count.

I see on some maps StandingCount goes to be 255, which make Movers bugged.

Proper solution must count Based Actors and use this number, since in map Base can be too set.

Possible affected maps (dirty check, can be StandingCount zero, when some actors in editor set Base to not None):

Binary file ..\Maps\CTF-'FTB-BigBallz.unr matches
Binary file ..\Maps\CTF-(PumpkinDelivery)-B1.unr matches
Binary file ..\Maps\CTF-BigBalls][.unr matches
Binary file ..\Maps\CTF-BigBallsIII.unr matches
Binary file ..\Maps\CTF-BoS-PoolFun-V1.unr matches
Binary file ..\Maps\CTF-LS_AFL_Footy.unr matches
Binary file ..\Maps\CTF-XV-Bania-v824-v1.unr matches

Binary file ..\Maps\CTF-XV-XtremeCraterV0.unr matches
Binary file ..\Maps\CTF-{}GDI{PLAYROOM.unr matches

Can be ignored for bStatic || (bNoDelete && !bMovable) actors, since StandingCount used only on delete or move actors.

In fact can be done by few easy loop, on map load. In first one - set all StandingCount to zero for all actors.
On next one - iterate over all actors, if on some Base not NULL - increase StandingCount on base.

Example of this bug.
How it must work:

smooth_lift.mp4

How it work with bug:

chopped_lift.mp4

You can even fall down from such lift if it enough fast:

fall_down_.mp4
