=head1 SYNOPSIS

Usage: launchpad.pl refresh shiptype "target"

Sends all available ships of type shiptype to target.

You must supply shiptype and target. Target should be of the form:

        "body_id:id_goes_here"
        "body_name:My Planet"
        "star_id:id_goes_here"
        "star_name:My Star"

Examples:
        "body_id:1"
        "body_name:Ud Vaijeu Eedd 4"
