Added Buyable POIs

[LukeZurg22]

About the PR

Fixes #191

Resolves a long awaited feature. It's solid on its own, though more Points of Interest should be added as time passes.

Currently, this only adds one buyable, with the rest remaining exactly as they are normally. It adds a Zombie UIV that contains some special items, most notably, a bottle of the Necropporozidonosol zombie cure.

This was written as of 20251202, meaning the actual content may change over time. Unlike standard PoI’s, Buyable PoI’s or BPoI’s must be deliberately purchased in order to appear in the map, and will not persist between rounds.
Once a BPoI is bought:
It cannot be sold.
A customized deed is either faxed to your ship, or spawned at the Monolith.
A customized stamp with your very own title is spawned at the monolith.
Note that it will not have the same protections as Primary Stations. Though server rules still apply, a good example would be that you can blow it up if nobody else is onboard.

All, // Placeholder value to represent everything
Scrapyard,
Laboratory,
Warehouse,
Farm,
Hospital,
Restaurant,
// Antagonist PoIs
Hideout,    // Defense Stations or Piratical Areas
Orbital,    // Armadan Defense Stations (See Guide on building Orbitals)

Make sure to check carefully behind the Monolith for a customized deed and stamp. The deed is decorative proof that you own your purchased PoI. Don’t lose it!

What Matters

• Added Purchasable PoI Menu at Monolith Entity (See NSB)
  Note: Works like a shipyard. Use your ID to facilitate purchase. Make sure to grab your stamp & deed hidden behind it. Currently still bought at Strange Signal, which needs updating.
• Added Zombie Research Lab PPOI / BPOI.
  Note: P/B means "purchasable" or "buyable" -Point of Interest.
• Added Guidebook Entry for Buyable POIs

Code Backend Things

• Corrected Floof Reference Source Folder to "_Floof`
  Note: The only thing from Floof that we have is Icecream. Nothing else, don't worry.
• Cleaned Frontier Shipyard Code
• Completed Frontier Shipyard Todo(s)
  Note: Made nicer with a couple methods.
• Fixed Monolith's Distance Reporter Code
• Added Niekroniak Names Dataset
  Note: Completely unused as of 20251203. Maybe one day when Armadan invasions are implemented, this will come in handy.

Breaking Changes

Those on Frontier/Ship -centric forks will inevitably run into merge conflicts regarding the numerous changes to the Shipyard and other related systems. To that I simply have to say that I wish you the best of luck. In fact, I wish myself and the Null luck in porting features in the distant future from elsewhere given those very same merge conflicts.
