Finish up library tests (#1120)
* Add tests for markdown-clj and tools.namespace

See comment for why only one markdown test could be run.
Closes #1069 and #1064

* Convert 10 test libs using add-libtest

Also improved add-libtest to only require maven artifact
and rely on clojars for getting git-url most of the time

* Convert 8 more test libs using add-libtest

Also updated table and added comment for newline test

* Fix doric test

* Disable tools.namespace test that fails on windows

* Added dozen manual test libs and converted 2 test libs

add-libtest.clj supports manually-added and test-directories options

* Converts last tests to test namespaces and write libraries.csv

* Add a number of library tests from projects.md

Also add more docs around adding test libs and tweak add script

* Use :sha for gitlib and older clojure cli

* Revert "Use :sha for gitlib and older clojure cli"

This reverts commit c663ab8368.

* Fix and disable failing tests

Disabled tests that fail consistently and fixed windows one
