Implementing missing features...
JIRA issue: CORE-13950
- Add WM_DEVICECHANGE message handler in the shell window to detect
  DBT_DEVICEARRIVAL and DBT_DEVICEREMOVECOMPLETE.
- Use GetLogicalDrives function to detect drives.
- Use SHChangeNotify to send SHCNE_DRIVEADD and
  SHCNE_DRIVEREMOVED notifications.
- Modify CDefView::OnChangeNotify.
