Suggestuib: Add Prone position.

Hi i would love that soldiers can go prone in some situations.
Would make it even more realistic. and it can be usefull in some situations.

We've received some community feedback on a prone feature already, and I've made a note for our team.

With that being said, we have a heavy focus on CQB (especially on the move) and prone wasn't as useful in the stories that were shared with us. Of course, there are exceptions to this, but this was generally the case.
