Wayne Stambaugh ebd53cd45c Eeschema: fix text justification terminology. 
Use justification instead of orientation relative to the anchor point when
describing text direction and alignment.  This seems to be the preferred
method by most users so hopefully this will eliminate some confusion.

Fix a bug in the s-expression schematic parser that failed to take into
account how graphical text alignment is defined for graphic text objects
compared to label text objects.
