v2.2.0: Merge pull request #2 from 0x450x6c/master

• Updating bundled straight.el version

v2.1.0

• Updating repo generation stage
  Previous implementation had a fatal flaw: straight-recipes-retrieve is
  only called when straight-use-package is called with a plain package
  name and there is no package override is registered.

  When a package is overridden or a plist is given to
  straight-use-package then the recipe is assumed to be complete and
  straight-recipes-retrieve call is skipped.

  New approach is to register our own override via
  straight-override-recipe for all packages so the recipe retrieval step
  is skipped so is the whole cloning stage because :local-repo is
  already set now.

• Logging style is also updated to be distinguishable from straight's own logs.

• Updating bundled straight.el version

v2.0.0

• abort when a package is not found
• users should (require 'straight) themselves
  This way consumers can actually provide defaults to straight before it
  is loaded, e.g. (setq straight-fix-org nil) will actually work.

v1.2.0

• make straight-vc-local-repo-dir work

v1.1.0

• New option to specify emacs package during build
• New option to fail build on unknown package
• Fix installing derivations using fetchTarball

v1.0
