Log:
[EXPLORER]: Simplify the creation of the tray band site and the tasks band.
- CTrayBandSite: Rename its constructor to CTrayBandSite_CreateInstance. Let the
CTrayWindow create the CTasksBand and pass it to the constructor. Use a standard com
interface to see if the tasks band was added while loading and don't use an explorer
specific interface for it. Make CTrayBandSite::_Init a bit clearer.
- CTrayWindow: Implement the IOleWindow interface and create the CTaskBand before creating
the CTrayBandSite. Then use standard com interfaces to get their respective HRND.
- CTaskBand: Rename its constructor to CTaskBand_CreateInstance. Remove a hack that was
using its IOleWindow to act like the IOleWindow of the CTrayWindow during the creation of
the CTrayBandSite. This is possible since the IOleWindow of the CTrayWindow is passed to
the SetDeskBarSite method of CTrayBandSite.
