Scrollbar and right window border (corrected)

When a scrollbar is on display in APP or TOD windows, the right
vertical border (outside the scrollbar) is not highlighted
when the window is selected.

The scrollbar is always highlighted:
- when APP or TOD is deselected
- in configuration windows where borders otherwise are not

The patch moves the scrollbar parameters (except highlight)
from arguments of draw_scrollbar() to the function itself.
The highlight argument was 1; instead it is set higher in
the call hierarchy (wins_update_panels()) and passed on down.
