FWA discreteDistance adjustements

[Drofseh]

Change FWA weapons that use yards to use metres.

For example
discreteDistance[] = {180, 275, 365, 455, 550, 640, 730, 820, 915, 1005, 1095, 1185, 1280, 1370, 1460};
Which is actually 200, 300, 400, etc, yards
Becomes
discreteDistance[] = {200, 300, 400, 500, 600, 700, 800, 900, 1000, 1100, 1200, 1300, 1400, 1500, 1600};
While this techincally makes the weapons less true to life, it's a significant QOL improvement since Arma is entirely metic.

I believe the inheritance is correct, but this should be built and tested for Updating Base Class type errors

• tested for UBCs

I also standardized white space in this file. Tabs to spaces, and opening brackets on the same line as class.
