spore v1.62.1

Fixed

• A handler that is a program was started from a turn without the operator's session: no
  XDG_RUNTIME_DIR, DBUS_SESSION_BUS_ADDRESS, DISPLAY, WAYLAND_DISPLAY or XAUTHORITY. A
  program that ran systemctl --user failed on create, the interaction stayed asked, and it
  went through only when spore tick handed it over, up to a minute later. A program that opened
  a page in the browser opened none. The runner now gives the handler those five from its own
  environment, so a handler behaves the same from a turn as from spore tick. A turn started
  where there is no display, over SSH for one, has none to give.

Changed

• A handler program started from a turn no longer gets SPORE_PATH, which it never got from
  spore tick.
• docs/interactions.md lists the environment a handler program runs in.
