Pesist Mouse settings, consider using DSBXinput

Consider using DSBXinput for advanced mouse and touchpad configuration.

Also, DSBXinput seems to give us a hint how to "persist" mouse settings across reboots. Not sure whether this is really the way to go as it feels less than clean.

> dsbxinput saves the current mouse/touchpad configuration in the executable shell script `~/.config/DSB/dsbxinput.sh`. If your window manager or desktop environment does not support XDG autostart, make sure the script gets executed on session start by adding the line `~/.config/DSB/dsbxinput.sh` & to your `~/.xinitrc`, `~/.xsession`, or your window manager's autostart file.
