#139 Multi-head focus fix.

[Jake Moilanen]

When running icewm on multiple heads, there is a bug
where if on display 1, there is a window(1) focused.
If you go over to display 2 and focus on another
window(2) the X input focus follows. When the mouse
returns to display 1, the X input focus is still on the
window(2) in display 2. If you click in the window(1)
on display 1, the input focus does not get set on that
window because ice still thinks it is focused. To get
the input focus back on the window(1) in display 1, you
must either click the title bar, or click another
window(3) in that display and then click back on the
original window(1).

Fixed in latest CVS.

I made my own patch, much simpler one that works better
especially when click focus is used. In that case, we should
not switch focus by mouse.
