don't inhibit power management when manually triggering suspend or hibernate

[kiddo]

Transmission currently inhibits gnome-power-manager's suspend and hibernate functions as longs as there is 1 "active" download (not paused).

However, I would need another level of logic: transmission should only inhibit "timed" actions, not "manual" actions. When I press the "suspend" button on my keyboard (or, in my case, when I close the lid of this laptop), I really "mean" suspend.

Today, I closed the lid while transmission was running because I had to GTFO, and a few hours later the battery was entirely drained. In situations like this, when I close the lid, I really mean to suspend, I don't care much what is running at that moment (anyway, when I fall out of range of the network, transmission will be useless).

So, to summarize:

• when the user starts the action manually: do not inhibit
• when the computer requests auto inhibition:

-- if downloads are active: inhibit -- if all downloads are paused: do not inhibit

Stupid trac breaks formatting. The summary should read:

• when the user starts the action manually: do not inhibit
  
• when the computer requests automatically (idle):
  

-- if downloads are active: inhibit
-- if all downloads are paused or complete: do not inhibit

the ​GNOME Power Manager Spec doesn't have this degree of flexibility, there's no way for me to implement this request.

You may want to set the "allow-hibernation-even-when-torrents-are-active" flag in settings.json to always allow hibernation.
