Make the powered off state customizable

Browse Source 
This changes the behavior of the powered off transition phase for the
Kobo devices: instead of displaying a confirmation dialog, a screensaver
is used after a 2 seconds press delay.

Users can specify separate directories/files/messages for the powered
off and sleeping states through the `path` and `message` attributes of
the `{poweroff,suspend}_screensaver` settings.

Fixes #2327 and closes #2306.
