Outputs failed tests to screen and / or file Allows to rerun only failed tests with minitest if added to Minitest::Reporters.use!

Example:

In test_helper.rb or similar:
Minitest::Reporters.use! [Minitest::Reporters::ProgressReporter.new, Minitest::Reporters::FailedTestsReporter.new(verbose: true, include_line_numbers: true)]
