Starting Parameters for Ships

Unless another rule says the ship starts with no shields, its starting shield level is:

Trunc(100 - 2*Damage/3)
                     ...if ship is Lizard
Trunc(100 - Damage)  ...otherwise

A ship's combat mass is:
```
Hull_mass + Trunc(ESB_Rate * Engine_cost / 100)
...plus 50 if ship is Fed
```
The Engine_cost is the monetary cost of one engine of the ship. The ESB_Rate is the sum of the following components:
- EngineShieldBonusRate if enabled (see AllowEngineShieldBonus, AllowESBonusAgainstPlanets)
- EModEngineShieldBonusRate if appropriate, see Experience. Note that this component even applies when the normal Engine/Shield bonus does not.

A ship's weapons are limited if the ship is damaged.

Beam_count =
   Ship_beams        ...if ship has Full Weaponry
   Min(Ship_beams, Max_beams - Trunc(Max_beams * Damage / Divisor))
                     ...otherwise

Tube_count =
   Ship_tubes        ...if ship has Full Weaponry
   Min(Ship_tubes, Max_tubes - Trunc(Max_tubes * Damage / Divisor))
                     ...otherwise

Bay_count =
   Basis_bays + Bonus_bays
   ...with
      Basis_bays =
         Ship_bays   ...if ship has Full Weaponry
         Max_bays - Trunc(Max_bays * Ship_damage / Divisor)
                     ...otherwise
      Bonus_bays =
         ExtraFighterBays + EModExtraFighterBays
                     ...if Basis_bays > 0
         0           ...otherwise

Divisor =
   150               ...if ship is Lizard
   100               ...otherwise

Max_beams, Max_tubes and Max_bays are the maximum amounts allowed by the ship's hull.
