/**
 * Function RemoteCommand
 * read a remote command sent by Pcbnew via a socket connection.
 * <p>
 * When user selects a module or pin in Pcbnew, Eeschema shows that same
 * component or pin and moves cursor on the item.  The socket port used
 * is #KICAD_SCH_PORT_SERVICE_NUMBER which defaults to 4243.
 *
 * Valid commands are:
 * \li \c \$PART: \c "reference" Put cursor on component.
 * \li \c \$PART: \c "reference" \c \$REF: \c "ref" Put cursor on component reference.
 * \li \c \$PART: \c "reference" \c \$VAL: \c "value" Put cursor on component value.
 * \li \c \$PART: \c "reference" \c \$PAD: \c "pin name" Put cursor on the component pin.
 * <p>
 * @param cmdline = received command from Pcbnew
