- Makefile: fixed odd indentation of "clean" target

- Makfile: added "install" and "uninstall" targets
- when deleting the currently active frame reference, reset active_ref of the
  frame, so that it can be set to a new value later
- during instantiation, circles were classified as arcs
- end point of KiCad circle didn't mirror the Y axis
