A3 gear

Refactored markers into two different functions. A generic setMarker would have been possible but too many parameters would be needed. For sake of simplicity and since group marker information is always the same for medics, I created a separate function.

Ace settings that I found by running an *ACE* search were removed

Missing file for gear template include has been added and obsolete template references removed.

Added NATO unit template for ease of use.

I checked the RPT log and found no hull related issues. Tested functionality in editor and found no issues.
