gss-poke by [Un]Inhibit doesn't work

adding the gss script and commented code to demonstraow it was used.  tried
inhibiting and uninhibiting the screensaver every time a face was detected, but
that didn't prevent gss from activating due to timer.  this is frustrating.

next i will try xdg-screensaver suspend / resume
