## Wait, isn't there a freeze right now?
Correct, there is a ship freeze currently, but I have received
permission from @Apogee-dev to create the PR for this vessel, as it was
a ship I've been working on since at least early-to-mid August.

If any other maptainer would like to overrule Apogee, I'd be more than
happy to temporarily close the PR. Until then, here it is!
## About The Pull Request
Hello everyone! Mr. SolGov here again to add yet another ship to be
tested!

This PR adds a completely new vessel, that being the **Inkwell-class
Supply Freighter**, a ship known for its vast cargo space!

With extra starter money, three sonnensöldners, and three miners,
players can enjoy completing bounties like no tomorrow, have drinks with
their crewmates in peace, and supply other SolGov vessels with much
needed equipment in less time than you can say "I ran out of ammo!"

Notable things in this ship include:
- Turrets (with IFF!)
- A bar!
- A full-blown cafeteria with a small kitchen and lounge!
- An office space for bureaucrats and scribes!
- Decently-sized quarters for the Logistics Deck Officer and Captain!
- A massive cargo bay with pre-existing supplies!
- A secret compartment for private storage!

And finally, as for jobs, there are:
- 1 Captain
- 1 Logistics Deck Officer
- 3 Sonnensöldneren
- 2 Space Engineers
- 3 Field Engineers
- 2 Bureaucrats
- 6 Scribes
<!-- Describe The Pull Request. Please be sure every change is
documented or this can delay review and even discourage maintainers from
merging your PR! -->

## Why It's Good For The Game
More SolGov content is nice! Especially when it comes to ships, for a
faction that only has two existing at the moment, haha.
<!-- Please add a short description of why you think these changes would
benefit the game. If you can't justify it in words, it might not be
worth adding. -->

## Changelog

:cl: PositiveEntropy

/:cl:

<!-- Both :cl:'s are required for the changelog to work! You can put
your name to the right of the first :cl: if you want to overwrite your
GitHub username as author ingame. -->
<!-- You can use multiple of the same prefix (they're only used for the
icon ingame) and delete the unneeded ones. Despite some of the tags,
changelogs should generally represent how a player might be affected by
the changes rather than a summary of the PR's contents. -->
