Title: add extended attributes for `:target` links

fixes #2847. This PR adds OS X-specific extended attributes
(metadata) whenever `:target` is used on an artifact. The
extended attributes are available for search software such
as Spotlight or Alfred to discover the artifact under the
`:target` name (rather than the source name)

Limitations: Spotlight specifically chooses to ignore this
attribute for App bundles. Alfred will also ignore this
attribute until the upcoming 2.2 release.
