Switch from Text::Markdown to CommonMark for parsing and formatting Markdown files (but not MultiMarkdown files). This allows code fences to work and generates nicer HTML in general, but is stricter about certain things. Add a test to be sure code fences are properly parsed and formatted.
Also update Build.PL to merge CPAN Meta spec 2 dependency specs, including test and development prereqs.
While at it, remove some old debugging lines from the tests.
