idle-monitor: Take idle inhibition into account

Browse Source 
Take idle inhibitions into account for when to fire idle watches as
requested by OS components.

This should stop gnome-session and gnome-settings-daemon considering
the session idle when they have been inhibited for longer than their
timeout, for example to avoid the screensaver activating, or the
computer suspending after watching a film.
