Add patch from Baranovskiy Konstantin about vertical justification of multiline texts. 

Fix issues created by this patch.
Note, this fix slightly changes the vertical position of these texts.
This is not really a  problem in eeschema, but in pcbnew this is perhaps  more annoying, if the verical multiline text is critical.
Fix a very minor issue  for vertical justification of single line texts in dxf import.
