-- Signals --
Thanks to the 'fsignal' patch available on suckless.org's website, we can easily write shell scripts to interact with dwm and therefore speedwm.
I made some changes to this patch, because it has some.. questionable behaviour in my opinion.

To use signals, simply use the speedwm-utils script. Syntax is speedwm-utils -exec <signum>

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