[gnome-control-center/wip/hadess/power-fixes: 6/9] power: Add Battery percentage preference

[Bastien Nocera <hadess src gnome org>]

commit 6a65dcf693a3c71d7554357b027d5cdc8de80d00
Author: Bastien Nocera <hadess hadess net>

    power: Add Battery percentage preference
    
    This matches the preferences available in a lot of other OSes, whether
    desktop or mobile, and can help with identifying the state of the
    battery quicker for some people, as a number might be parsed quicker
    than an icon/colour combination.
    
    Closes: #481
