Give the remaining tray applets their modules, each with one start

openrazer (the official driver, daemon and library), polychromatic (the
AUR tray, kept as found; its i3 line moves out of the i3 module into its
own node-display-session contribution), forticlient (the AUR VPN client:
its service declared, its configuration never read) and nm-applet (the
desktop half of NetworkManager, apart from the server-side module).

The openrazer daemon fails on both workstations because the account is
not in the openrazer group; openrazer_check names it and the README
carries the one-off step, since the account's user resource is zsh's.

desktop.go learns to tell a program from another sharing its 15-character
command name, so polychromatic's tools never count or end themselves, and
a copies test holds the six carriers to one text.
