Add Weapon Status Overrides

[UndeadZeratul]

With enough effort & time, the HCItemOverrides class should let me do what I need, similar to how the Stat Counters were made using a BaseCounter class and extending it from there. A core BaseWeaponStatus that has all the necessary hooks, methods, getters, etc. to draw every piece of the main/"standard" templates should suffice for the 80% of the weapons out there, then override the methods in the remaining 20% with whatever custom layout they use.

One suggestion for this HUD element was to have the extra magazines reverse their direction when renewing how full they are, so instead of rounds "lowering down from the top", they're instead "rising up from the bottom" of the mag. Should be as simple as adding a CVAR toggle for the durability bar direction
