Move to monorepo

🆙 Improvement proposal

Combine other Bearded. libraries into the same repository.

Context

Simplifies managing dependencies (both external dependencies and internal ones), and consolidates discussions and issues in one place.

NB: this does not propose shared NuGet packages.

Suggested approach

Preparation

• Migrate remaining libraries to OpenTK stable. We should probably pin them all on the same version.
  • This makes dependencies easier after merging.
  • It also includes a migration to .NET Core, which is needed for some of the steps below.
• Ensure all libraries use the same directory structure. I believe the structure used in Bearded.Utilities is standard.
• Migrate to GitHub actions. (See Migrate to GitHub actions #198)
  • Since the workflow will be generic (actually organisation-shared), it will transparently keep working if we merge the repositories.
  • I believe dotnet pack, which is what we are using in the GitHub actions, will automatically figure out the dependencies within the packages, and export those as NuGet dependencies.
• Ensure there are no more open PRs open on the other libraries.

Execution

• Using this repository as base, merge in the remaining repositories as if they were separate remotes.
  • Since we cannot migrate issues and PR history, it makes sense to me to use the library with the most history.
• Push this raw merged result directly to the main branch of this library.
• Create a PR that merged the sln files, and updates the cross dependencies between libraries.
• Rename beardgame/utilities to beardgame/beardkit to reflect it is now a bigger set of libraries.

Follow-up

• Move all the open issues from the other libraries into this repository.
• Move all the old repositories in an archived, readonly state, to maintain the closed issue and PR history.
• Discuss further splitting Bearded.Utilities in smaller NuGet packages.
