Closes: #157 XDG portals expose a D-Bus interface allowing apps to prevent screen idling, user switching, and other actions. That interface, org.freedesktop.portal.Inhibit, does all of the heavy lifting here. Idling = the screen dimming or shutting off. Idling is inhibited when a video is actively playing. Idling is NOT inhibited when videos aren't playing - this includes paused or stopped videos.
