Create Buildings!

New things this week:

1. Small resources scattered in sectors:
   1. Now they appear at the same time that a map sector is fully visible.
      1. Before, they appeared a second after discovering a sector, which looked weird since they appeared suddenly out of nowhere.
   2. There is more variety of resource types in each sector biome.
   3. Also the quantity of small resources gets saved: if you enter the same sector twice, you'll see that the quantity of resources stays just as you left it.
2. Added a new action to see the resources of the terrain while you explore.
   1. This resources will be used to increase the population of the different bases in the planet.
   2. To increase the population you will need to build structures on top of these resources to gather them.
   3. Each base will have different resource requirements to increase its population.
3. Added the ability to build structures to extract resources from the sector.
   1. These resources will be used to increase the population of each base.
   2. Each base will have its own requirements to increase its population, so these buildings will be used to meet those requirements.
   3. This does not work very well yet, it has some bugs and it's not completely implemented.
4. When you hover over a base you can see its available resources inside a tooltip.
   1. Build structures to increase the quantity of resources.
