New features and improvements:
- Module Export/Import: Share custom modules with peers! Export by right-clicking any custom module and selecting "Export Module". Creates a self-contained folder with all media files. Import by placing exported folder in imported_modules/ and restarting. Auto-loads modules from imported_modules/ on startup.
- RSS Feed Notifications: Stay updated with new teachings and events! RSS button on toolbar with red highlight for new content. Card-based view with Previous/Next navigation. Mark items as read/unread with persistent status between sessions. Enable/disable RSS feed with manual refresh option.
- Technical Improvements: Added exported_modules/ and imported_modules/ directories. Module paths now use filenames relative to JSON location for portability. Auto-detection of imported modules on application startup. RSS feed parsing with QXmlStreamReader. Persistent settings with QSettings.
