++pcbnew
+    specctra_export.cpp: added DSN 'outline' support from EDGE_MODULEs.
+    lines and circles, not arcs.
+    factored out EDGE_MODULE::ShowShape() from EDGE_MODULE::Show().

-	added : full text conversion between text, label, global label and hierarchical label
-	some problems fixed:
-	- annotation incorrectly cleared.
-	- reference not copied in component copy.
-	- incorrect redo when changing the chip name in component edition
-	
-	bugs not fixed:
-	- incorrect annotation in complex hierarchy with multi parts per package (duplicates created).
