Implement Sponsor Mode

[mokun]

Is your feature request related to a problem? Please describe.

• A sponsor may own a few settlements in mars-sim.
• Currently, in Sandbox Mode, a player has access to all settlements and all sponsors.
• In Command Mode, a player is supposed to have access to one settlement only.

Describe the solution you desire to see

• In Sponsor Mode, a player becomes a sponsor with manpower and resources in his disposal for developing the planetary infrastructures and enabling commerce between colonies on the Moon and Mars.

Specifications (please complete the following information):

• pre 3.7.0 build 8781

Additional context

• Allow interactions with other sponsors in CommanderWindow - https://github.com/mars-sim/mars-sim/issues/648
• Create a sponsor combobox for Sponsor Mode as proposed in https://github.com/mars-sim/mars-sim/issues/903
• Incorporate ideas regarding sponsor tasks from #898
• Implement ideas from #363

@bevans2000

I've just added the Sponsor Mode by adding SPONSOR in GameMode enum class.

So, may be you'd like to design the settlement/sponsor combobox in such a way that when the GameMode is SPONSOR, then add all the ReportingAuthority objects as the elements. Otherwise, add Settlement objects as elements.

I suppose we'll need to beef up the use of ReportingAuthority and Nation very soon to do all sorts of interesting things.

They should be able to own resources that influence or dictate the course of actions of the settlements they own, etc.

Anything else you can think of that we need to address as we go down this lane ?

@Urwumpe, What do you see as the number one and number two things along the same vein that you would like to see to get implemented in near future ?

My TOP3

1. Define objectives for settlements
2. Plan launches to Mars
3. Prepare research projects and questions

Will we allow commercial exploitation of Mars?

Define objectives for settlements

We can take what's being defined currently in a sponsor's mission agenda (objective, findings, capabilities, and data rights, etc.. See governance.xml) and quantify them into real goals that are number-based and can be tracked.

I suppose these goals will be sponsor's goals for each settlement.

We can create some sorts of a compliance score to gauge how well the goals are being fulfilled.

May be we can have a loyalty score between a settlement and its sponsor when modeling interesting dynamic between them.

On top of that, a settlement's commander should have the flexibility to formulate his own goals that may align with the sponsor's or deviate from them.

So it's entirely conceivable that initial interdependence of a settlement on its sponsor will shift over time.

Say when a settlement is sufficiently developed and has forged successful relationship with other settlements, the sponsor may adopt a appeasement strategy to avoid the settlement from forming its own government or uniting with other settlements to create a new governmental bloc or political entity on Mars, or even switching to come under another sponsor or corporation's control if it's possible.

I think we can integrate this into revisiting what the GamesManager class does. What we should do is create a replacement class to cover Commander mode, Sponsor mode and sandbox mode. The latter being unrestricted. It should be applicable to just the UI and Console.
