Added "external-text-formatter" test case

* test case requires markdown.pl formatter to be available in "/usr/bin/"
* updated README.md to mention "external-text-formatter" instead of "execute"
* updated "read-directory" test case reference file
* included library resolution test into "read-file" and "read-xml-file" test cases
