From 9966d0a83ad7cf5ea76a04f31912e92908f3da63 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Hide ClearGrab/CloseGrabs actions behind an option

Similar to how we put the Terminate mapping behind an option rather than
enabling it by default, put the ClearGrab/CloseGrab action handlers
behind an option too, so we don't ship 'break my screensaver'.  Oops.
