river: Add init reload without program restarts

By passing the 'no-restart' argument as the first parameter of the river init
file, we can prevent program restarting which we do not want to have restarted
every time (e.g. kanshi, wlsunset, waybar, swayidle, etc)

By default these programs will still always be restarted. However, passing the
parameter means that if the program is already running, we do not restart it.
If the program is not yet running it will still be started like normally.

The functionality makes use of the `pidof` program, so on Arch it requires the
'procps-ng' package. This is by default installed as a requirement for the
'base' package group.


Reverted changes from earlier wallpaper switch.
