When using large taskbar icon:
- Increase the padding around system tray icons.
- Push the clock text further to the right, increasing the left padding
between the clock and notification icons.
This matches Windows 7 shell behavior.
- Correct the spacing for the clock area, in the case when bPreferDate is
enabled, only two lines are visible, and the day of the week is shorter
than the date.
