* src/screen.h (is_a_root_window): new prototype

* src/screen.c (is_a_root_window): new function

* src/events.c (property_notify): check for ratpoison commands on
every root window, not just the default root window.

* src/communications.c (send_command): store the root window in a
variable, root. and use it whenever the root window is needed.
