[Module::Build] (RFC) (PATCH) META.yml Specification Update

[Randy W. S. <Ra...@Th...>]

Ok. So, I've gone over the spec and referenced this thread and my 
archives of past meta discusions on module-authors, and I've come up 
with a preliminary patch for Ken and anyone else interested. This is a 
patch against <http://module-build.sourceforge.net/META-spec.html> which:

* Added more YAML rationale articles.
* Fixed existing link to YAML discussion thread to point to new 
<http://nntp.x.perl.org/group/> site.
* Added and deprecated the "private" field.
* Added "abstract", "configure", "requires_os", "excludes_os", and 
"no_index" fields.
* Bumped version.

Comments and suggestions?

Randy.
