New features

• Renaming now supports names involving inherit.

  • Renaming identifiers inside inherit will change the definition, and
    foo: { inherit foo/* -> new */; }
    =>
    foo: { new = foo; }

  • Renaming identifiers outside inherit will change references.
    foo/* -> new */: { inherit foo; }
    =>
    new: { foo = new; }

• Show documentations during completion for builtins.

  Currently only global builtins like map are supported.
  The documentations are generated from Nix at build-time, and some
  builtins don't have upstream documentations.
