- Check that all frames are valid before using them - Added an error page to MiniBrowser.
- Updated the OnBeforeClose event in all demos using TChromiumWindow to send a WM_CLOSE message instead of calling "close". - Fixed all MDI demos. Now the demo will not close automatically when the last browser is closed manually.
- Converted almost all the demos to Lazarus thanks to avra - Reorganized "demos" directory.
