* Stop packaging `Resources/ServerInfo`
This is only used by the client, it is unneccery to pack into the server. Plus it keeps getting people to think that just editing the server resources will modify the guidebook even though that needs a custom dev enviroment.
* Add credits too
* Configuration argument for content packaging
Needed this for something so here we are. I think someone mentioned they wanted this? Welp its here now
* Add client, tiny fixes
* Give .props files 2-space indents.
* Move to Central Package Management.
Allows us to store NuGet package versions all in one place. Yay!
* Update NuGet packages and fix code for changes.
Notable:
Changes to ILVerify.
Npgsql doesn't need hacks for inet anymore, now we need hacks to make the old code work with this new reality.
NUnit's analyzers are already complaining and I didn't even update it to 4.x yet.
TerraFX changed to GetLastSystemError so error handling had to be changed.
Buncha APIs have more NRT annotations.
* Remove dotnet-eng NuGet package source.
I genuinely don't know what this was for, and Central Package Management starts throwing warnings about it, so YEET.
* Remove Robust.Physics project.
Never used.
* Remove erroneous NVorbis reference.
Should be VorbisPizza and otherwise wasn't used.
* Sandbox fixes
* Remove unused unit test package references.
Castle.Core and NUnit.ConsoleRunner.
* Update NUnit to 4.0.1
This requires replacing all the old assertion methods because they removed them 🥲
* Oh so that's what dotnet-eng was used for. Yeah ok that makes sense.
* Add Robust.Analyzers.Test
* Update submodule
* commit to re-run CI
