Converting to .NET Core / 5 / whatever

[kf6kjg]

This is going to be a bit of work. Several of the NuGet packages in use have died in favor of .Net built-ins. Conversions will be needed.

NuGet Packages

• Nancy: everything it provided should be now part of .NET.
• Trove.Nini: There's nothing in .NET. We should consider moving to a better config format, say YAML or TOML. I'm not a fan of XML configs.
• LibreMetaverse: Exists in legacy .NETStandard. Should be usable.
• NUnit: Exists in legacy .NETStandard. Should be usable.
• RestSharp: Exists in legacy .NETStandard. Should be usable.
• zlib.net: Needs replacement. It is suggested to convert to SharpZipLib.
• Chattel: Needs an upgrade itself.
