Issue #3444468: Updates documentation and test scripts for clarity
I wanted to make the docs a little easier to read and do a little test script tidying.
- The main README.md has more styling a few language changes
- The script README.md has line breaks removed
- The 10000-item script has been renamed for clarity. Maybe it's my bad eyes, but TestDo10kThings.php and TestDo10Things.php were harder to distinguish.
- The language of the script logs and comments has been more aligned with their intention or content.
