Interaction - Add remote squad management

[PabstMirror]

Idea from @Drofseh

• Allow dropping and changing team colors of any unit in player's squad
• Remove/Replace Interaction - Add action to drop distant units from group #10228
• Added setting

I think Assign White would be better than Leave Team.
Leave Team could be intepreted as removing them from the group rather than removing their colour.

I think Assign White would be better than Leave Team. Leave Team could be intepreted as removing them from the group rather than removing their colour.

Leave team is what's currently in use in the team management interactions. However, I do agree, it would be better to update both to Assign White, it's less confusing that way.

Could assignedTeam returning "" be problematic?
From what I can gather it seems like all functions in which it could be problematic have already have measures in place to deal with it.

It used to give nil which caused problems

String (or, prior to Arma 3 v1.94, Nothing if given unit is objNull or remoteControlling another unit)

But I think just getting "" should be ok

[PabstMirror]

should this have (_unit == leader _unit)?

[johnb432]

It probably should.
