Fix 5193: Weapon Bays only work at Short Range

[Sleet01]

This was more fallout from changing the getMaxRange() function signature: BayWeapon and InfantryWeapon both were overriding the single-argument version, so switching to the two-argument version caused the base WeaponType function to be called instead.

Testing:

• Added a new unit test to confirm override is working correctly.
• Re-ran all unit tests (some MekHQ tests still failing, unrelated).
• Tested using @pheonixstorm 's save and confirmed correct ranges on various weapon bays.

Sure, but what's the rationale? I don't see it in the style guide...

Thanks. I'll put it in the style guide.
