[Feature Request] Add "FORCE_FACEWEAR(rif)" to gearscript.

[Bubbus]

Is your feature request related to a problem? Please describe.
Add a way for a specific gearscript to override a player's facewear choice. Useful for gas masks and stuff.

Describe the solution you'd like
Add a "FORCE_FACEWEAR(rif)" to the gearscript macros set. This should indicate that the gearscript should force the facewear from the loadout array onto the given unit.

Why is this this best way to solve the problem?
Lets you set this option on a per-gearscript basis, for example regular soldiers and CRBN soldiers.
