Block rotate and mirror now work like they do in Pcbnew (that is
they're treated as part of the block move/duplicate/whatever
rather than finishing it).

1) when duplicating don’t keep original hidden until end of drag
2) reset selectionArea when showing it so it doesn’t flash in its previous location
3) center a pasted block on the cursor
4) don’t draw the source selectionArea when pasting a block
5) implement selection-style highlighting for contents of blocks
6) add pasted items to view so they don’t disappear when the block is placed

Support all symbol orientations. (Yes, SCH_COMPONENT said only the
first 8 were used, but it lied.)
Fix cases where SetTextAttributes() was overwriting previously-
set justifications.
Correct rotation of vertical text.
Fix issue where bold global label would affect thickness of next
label's outline.
Eeschema (where only the parent component is in the view) uses
draw order.
LibEdit (where the individual items are in the view) uses the
viewPriority setting.
