1) Fix repaint glitches wrt to the solo window header when window docking is enabled. The glitches were occurring because windows move to the kShellWindowId_DockedContainer for the duration of a drag and windows were not properly repainted
2) Change the behavior of the solo header such that:
- Docked windows never use the solo window header
- Windows which are not docked cannot use the solo window header when there is a docked window (There must be exactly one window onscreen in order to use the solo window header)
- A window can use the solo window header when it is being dragged even though it is in the kShellWindowId_DockedContainer
