Master: ShipMeta: Created preliminary metadata

  More is likely to come, but we now have:
    HP
    SP (shields)
    EngineVals
    Target setting
    Firing
    Taking damage
    Dying
  all as base methods that require expansion.

  Lots of get and set methods.

  Also a ShipType enum which will be used to work out stats.
Master: All values I made up should now be initted
