Service command handling fix when no upstart config file

    Fixed the service command not working

    On Ubuntu 1[02].04 the service name was not recognized because
    there is a SysV style init script, but not an upstart config file.

    Example: The `ntp` client.

    Also removed extra spaces at the end of the lines, while at it.

This allows minor changes to be handled by adding a new
parse line function to the subclass

Now all BSD network classes directly inherit from Network as well as from the generic BSD network class.  This removes the need for itersubclasses().
