Explosives - Add ability to attach explosives to objects

[DartRuffian]

When merged this pull request will:

• Add a config flag to allow explosives to be placed on any non-unit object (e.g. houses)
  • M112 and the M183 can be attached to objects (vibes based, maybe not the M183 though)
  • This does have issues where units can place/attach explosives inside thin walls (like doors), but this also happens with vehicles anyway
• Add common function to check if something is a terrain object

IMPORTANT

SLAMs, demo black might good for object attachable as well

[DartRuffian]

I was gonna do the SLAM but it's rotated 90 degrees so I just left it off

Found an issue while doing some more testing, seems like trying to attach them to terrain objects causes them to be sent to the debug corner Resolved by using a dummy object when attaching to terrain objects

Needs docs, but that's easy. Can do that after property name is picked Done

[DartRuffian]

Name was changed to make it clearer, I'm happy with it now

Is there a reason not to use https://cbateam.github.io/CBA_A3/docs/files/common/fnc_isTerrainObject-sqf.html instead? I'd prefer to not add a public function if we can avoid it.

[DartRuffian]

I didn't know it existed, and seemed like common enough utility to just make it a public function

[DartRuffian]

Just checked the CBA one, it's doing a nearestTerrainObjects so its decently slower than just checking net id:

player call CBA_fnc_isTerrainObject; // Execution Time: 0.0041 ms  |  Cycles: 10000/10000  |  Total Time: 41 ms
player call ace_common_fnc_isTerrainObject; // Execution Time: 0.0037 ms  |  Cycles: 10000/10000  |  Total Time: 37 ms

I'll swap it to the CBA one, and PR changing the CBA one to check net id
