Identification of spaceship's Habitation Modules and Life Support Modules

The spaceship sprites come from a sprite sheet (data/misc/space.png):

Freeciv spaceship sprite sheet

Excerpt from this sprite sheet's spec file (data/misc/space.spec):

tiles = { "row", "column", "tag"

  0,  0, "spaceship.solar_panels"
  0,  1, "spaceship.life_support"
  0,  2, "spaceship.habitation"
  0,  3, "spaceship.structural"
  0,  4, "spaceship.fuel"
  0,  5, "spaceship.propulsion"
  0,  6, "spaceship.exhaust"
}

Therefore:

Freeciv spaceship's life support module is the life support module.

Freeciv spaceship's habitation module is the habitation module.
