- make printer::printerdrake::install_spooler() work with an optional $in

- many functions now take $security (which used to be taken from $in during install)
- fix some functions with empty prototype but still using a parameter
- remove some unused variable
- rename some $_foo vars to $foo since those vars are used
- add some undef to some function calls to be minimally perl_checker compliant
- perl_checker compliant optional parameters in start_spooler_on_boot(), install_spooler()
