Reorganize command line interface

haikuporter's command line interface has options for actions and options that just modify the behavior. It would be nice to reorganize the interface such that the actions become non-options and the first parameter. E.g. "haikuporter patch foo", "haikuporter package -j8 foo", etc. This would make the interface easier to understand.
