109.18.00

- a number of improvements to `inline_tests_runner`, including a
  `-verbose` flag.

  1. Made pa_ounit errors more readable.
  2. Added `-verbose` flag.
  3. Made the `-only-test` locations compatible with those displayed
     by the `-verbose` flag.
  4. Renamed `-display` as `-show-counts` to avoid confusion with
     `-verbose`.
  5. Improved errors when parsing the command line.
  6. Updated the readme.
  7. Added a `-list-test-names` which shows what tests would be run,
     if this option was not given.
