0.5 Status: Products finalization, Colony's Storage and Reserves

Finally, the data structure concerning the products is now completed, and 18 products (all resources) are added.
The colony's storage and reserves are also implemented.
The colony's storage concerns the global products storage of a colony for industrial and commercial uses. The capacity depends directly on the colony's infrastructures.
The colony's reserves, for the oxygen, food and water, concerns the reserve the colony's population can access for a direct use. Depending on the orbital object's ecosphere, where a colony is settled, a reserve can be useless or required.

And now it's finally time to update the interface with the settlement's infrastructures trees.
