[wmii] bar on top

Hello,
for some strange reason I've always liked my bar on the top of the
screen.
For those who share the same preference with me, please find attached
a patch for the wmii-20060501-rc1-prypiat release candiate, which will
enable the bar on top of the screen as a compile time option using
% make BAR_ON_TOP=1

Regards Alexis.
