Public historical copies of the 1.x spec

This is an initial cut of adding publicly indexable copies of the old meta specs.  The 1.0 and 1.1 specs have been converted to pod with a minimum of formatting changes.

The intention of this is to have a the older specs available on CPAN in an easily referenceable format, and that they could be updated to better reflect reality.

Specifically, the license field refers to Module::Build for the list of allowed licenses.  The way Module::Build handles licenses has changed over the years, so it isn't an accurate reflection of what was allowed when the spec was published.
