hlwm patches

[Florian Schmaus <flo _at_ geekplace _dot_ eu>]

Hi,

Patch 1 und 2 are meant to extend herbstclient when used as message
source for a panel applet. For example you can now use

herbstclient -0 -l -i '(focus_changed|window_title_changed)'

as *null character* delimited String source of the current window
title. Side Note: I'm currently building such an applet for mate,
gnome2/3 and xfce4.

Patch 3 is simply another FAQ entry bragging about how easy it is to
create a IM layout with just a few lines of 'herbstclient' code, where
other window managers need whole modules. :)

Finally Patch 4 is a dmenu run script that places the windows in the
tag that was active at the time the script was invoked.

Best
 Florian
