Second Update for Java Web Viewer

✅ Fixed filename loading (auto redirect index.htm → file:///)

✅ Safe parsing (no more crashes)
✅ Added some basic debug details to console e.g. if an icon was loaded successfully
✅ Added App Icon as a template (icon.png)
✅ Icons can now be assigned (local PNG/ICO files or auto for favicon)
