Limit messages sent to the text chat to nearby players only

[LordDz]

Voice commands from the menu are currently sent to all players in the team, this limits the effectiviness of the commands. It also spams the text chat if someone feels like spamming 'Sniper!'

I feel like it would be much nicer if voice chat command text messages were proximity based as well. The ATTACK, DEFEND, UNDERATTACK and HELPAT commands will still be sent to the chat regardless of distance.

Messages like "Sniper!" "Grenade!" "Go Go Go!" "Enemy AT Soldier!" will have more meaning when you see them in the chat.¨

I would suggest we try this on a beta test, on a close infantry map as well as advance maps. Just to get the feel of it.

Make sure that the naming conventions are all in line with the style guide (CamelCase, not camelCase).

I tested it out locally, 180 seems too far. 100 meters should be fine. Sorry this took so long to get to!
