-- Fsignal --
Thanks to the 'fsignal' patch available on suckless.org's website, we can easily write shell scripts to interact with dwm and therefore speedwm.
This is exactly what I did and speedwm-utils, speedwm-swal, speedwm-shutdown and more take advantage of it.

In order to use 'fsignal', your system must have 'xsetroot' installed.
Then simply use the dwm-utils script. Syntax is dwm-utils -exec <signum>

Below is a list of all signums and what they do.
