	* app/properties.[ch] : renamed to properties-dialog.* to have unique
	filenames (avoids debugger confusion)
	* app/Makefile.am app/makefile.msc app/makefile.mingw
	  app/commands.c app/defaults.c app/diagram.c app/diagram_tree.c
	  app/modify_tool.c : adapted accordingly

	* app/properties-dialog.c : restored nullification of the static 
	'object_part' on dialog destroy to avoid double destruction
