Interaction - Add interaction with terrain objects

[Dystopian]

When merged this pull request will:

• title;
• add dev function for replacing any terrain object with hotkey.

Terrain objects with ace_interaction_replaceTerrainObject config value == 1 are replaced with created object when interaction menu is being opened near them. This feature can be useful at least for dragging, acex sitting and acex field_rations.

What happens when terrain object is a large building and somebody is inside it?

Even on small objects, any chance for offsets, blowing things up inadvertendly etc.?

What happens when terrain object is a large building and somebody is inside it?

The largest "building" I tested and implemented is Land_BusStop_02_shelter_F (the bus stop on Chernarus 2020 and, I suppose, on Livonia), see acemod/ACEX#255. It works OK and nobody even see object replacing (including those who's inside it). Anyway I don't think replacing of large buildings is a good idea.

Even on small objects, any chance for offsets, blowing things up inadvertendly etc.?

There is a small chance of objects colliding. At least I saw plastic chairs falling to ground when replaced. But I don't think it's a big issue. And also the setting is disabled by default.

I think that's pretty neat then!

Code looks good to me.

This is a little rough because of physX.
On stratis beach the "sun chairs" went flying into the ocean because of collisions.
note: I forgot to test, but maybe adding a frame delay between hide and create would help?

but it also adds a lot of functionality, it is default off and the setting has a warning, so I think it's ok to merge

I found these chairs and now I hate them. Neither delay (even for some seconds) nor any of [fixCollision, fixPosition, fixFloating] functions help.

Bug looks VERY strange. Repro:

1. place player on Marina Bay beach exactly near single chair but not close to other 2 chairs:
   
2. press interaction key, observe single chair replacing
3. go close enough to other 2 chairs and press interaction
4. sometimes observe chairs strange behavior: floating, flipping, flying for some meters.

If skip step 2 I can't repro.

I am good to merge this.

Regarding physics issues:

• It's disabled by default
• It has a warning on the setting
