* last change to player.ship.manifest: manifest.food & similar are now read/write manifest quantities. Internally all commodities are now going to be referenced by the canonical identifiers, commodities.plist still overrides the displayName - the .manifest.list array is unchanged, and still read-only.
* renamed 2 ship properties for consistency: ship.availableCargoSpace & ship.cargoCapacity now become ship.cargoSpaceAvailable & ship.cargoSpaceCapacity.
- more code tidying.
