Recorder updates and a fix for the edgedriver install script

• Add a console script option to create a file for Recorder Mode:
  -- sbase mkfile NEW_FILE.py -r
  -- (Works with -r, --rec, --record, or --recorder)
• Fail fast if using Recorder Mode without Chrome or Edge:
  -- (It's a Chromium extension, so only Chromium is supported).
• Fix the "msedgedriver" install script (a new file was added).
  -- Usage: sbase install edgedriver
• Update Firefox settings and behavior:
  -- Set browser.privatebrowsing.autostart to False.
  -- Also fix a Firefox issue with the :contains() selector.
• Improve the script that detects and displays JS errors:
  -- Simplify output, and only display one error per line.
• Update the tool that scans for broken links on a page:
  -- Ignore *://fonts.gstatic.com/*
• Refresh Python dependencies:
  -- rich==10.12.0;python_version>="3.6"
  -- coverage==6.0.1;python_version>="3.6"
