v3.0.3-stable

Improvements

• Upgrade Moodle 5.1
• Convert content.js to an AMD module and load it on every page via a hook, so video popups, image lightboxes and flip cards keep working without an active Atto or Tiny editor instance
• Convert editor.js to an AMD module so it loads correctly when Tiny is initialised in a block or assignment via the fragment/AJAX API
• Security Review : XSS, CSRF / Authorization, IDOR / Authorization, Input Sanitization
