Giannis Adamopoulos 2ed535da8a [EXPLORER] -Rewrite taskbar settings routines and dialog 
- Rewrite the taskbar settings and start menu settings property sheets.
- All settings in the taskbar settings property sheet can be loaded and saved properly except for the quick launch one which will be implemented later.
- Implement toggling lock, autohide and always on top. The rest will be implemented later.
