Different options for fuel generation

[ekolis]

Describe the feature you'd like to see
An option at game setup to toggle fuel generation between "starbases generate infinite fuel" (current behavior), "fuel can be mined from planets like a resource" (old versions of Stars!), and "both".

Benefits
More options are fun!

Describe alternatives
Could make it two checkboxes and prevent the game from being started if both are unchecked...

Additional context
N/A

or a hybrid? fuel is a mined resource, but Starbases auto-distribute to ships?

I like the idea of having a fuel production stat, but it'd need to be something you can increase.
