Fatigue Overhaul
Inspired by: Better Fatigue Usage

Formula for fatigue cost (based on experimentation):
fFatigueAttackBase + fWeaponFatigueMult * weapon weight * swing length
Swing length is between 0 (for an tiny swing) and 1 (for a full swing)
Default values:
    fFatigueAttackBase = 2
    fWeapon FatigueMult = 0.25
New values:
    fFatigueAttackBase = 20
    fWeapon FatigueMult = 1
----------------------------------------------
Fatigue is restored at the following rate (even while running):
    FatigueReturn = fFatigueReturnBase + ( ENDURANCE * fFatigueReturnMult )
Default values:
    fFatigueReturnBase = 2.50
    fFatigue ReturnMult = 0.02
New values:
    fFatigueReturnBase = 30
    fFatigue ReturnMult = 0.15

Fatigue caused by running is calculated as:
    RunFatigue = fFatigueRunBase + ( fFatigueRunMult * ( CurrentCarryWeight / MaxCarryWeight ) )
Default values:
    fFatigueRunBase = 5.00
    fFatigue RunMult = 2.00
New values:
    fFatigueRunBase = 30.00
    fFatigue RunMult = 10.00

fWeapon FatigueMult = 1

fFatigueReturnMult = 0.15
fFatigueRunBase = 30
fFatigueRunMult = 10
fFatigueSneakBase = 6
fFatigueSneakMult = 6

fFatigueSwimRunMult = 13.5
fFatigueSwimWalkBase = 13.5
fFatigueSwimWalkMult = 5
