feat(0.7.2): screenshots + correct wp.org contributor handle

Two small submission-prep moves on top of v0.7.1:

Added
- Five screenshots at the plugin root, per WordPress.org convention:
  screenshot-1.png  Dashboard widget
  screenshot-2.png  Settings page
  screenshot-3.png  History page (star + four search-provider links)
  screenshot-4.png  Pop-out mini-player window
  screenshot-5.png  About page
  Sizes 1087–1422 wide; total ~720KB.

Changed
- Contributors: in readme.txt updated from `davidtkeane` (placeholder)
  to `ir240474` (actual wp.org username, profile confirmed at
  https://profiles.wordpress.org/ir240474/).
- Stable tag: bumped to 0.7.2.
- Screenshots section in readme.txt rewritten to match the five
  actual screenshots.

Notes
- Source images were in an images/ working folder; moved + renamed to
  plugin root for wp.org convention, working folder removed.
- After this release the only PCP residue is the .gitignore
  hidden-file warning — unavoidable on the dev install, won't be in
  the submission zip.

Files: radio.php (version), readme.txt (Contributors / Stable Tag /
Screenshots section / new 0.7.2 changelog + upgrade notice),
CHANGELOG.md, inc/about.php (rotate v0.7.2 → latest),
5 new screenshot-*.png files at plugin root, images/ removed.
