Adds some of the missing battery icons

Merged Philip Müller requested to merge sdwolfz:add/missing-links into master

Created by: sdwolfz

Sorry for the late PR, I made this a while ago and I don't remember exactly from which directory I copied the files, I'l try to remove the copies and replace them with symlinks if there's no hurry.

There are still some icons that I have yet not replaced, will do so in the future with a different PR.

Here is a screenshow of how it looks now on my XFCE laptop: screenshot_2018-01-10_00-04-55
