Fixed script view default font inconsistencies
Added a hidden preference option to define options for makepkginfo.

These options are used when importing new items. The preference key is named makepkginfoDefaultOptions and should be an array of strings. This preference option can be set with the defaults command. For example:
$ defaults write fi.obsolete.MunkiAdmin makepkginfoDefaultOptions -array --catalog "my-custom-catalog" --catalog testing
