[PATCH] Fix plus icon position based on the theme

[Giuseppe Bilotta]

From: Tomaz Canabrava <tomaz.canabrava at intel.com>

I hope this time I got it right. basically, the old code
tried to guess where the plus icon should be with a fairly
bad set of defauults.

This one patch asks for the Qt style where everything is and
uses that knowledge to make it be in a more sane position.
