Added changes to admin.module and system.install, so that certain system values are setup
by default. This was causing a bug, if they weren't set, which on some systems created

Fixed a small typo, and fixed a bug in _FlightPath.php. Made it so that courses
worth zero hours may be repeated infinitely. The bug, otherwise, was to not allow
repeated attempts, which doesn't make sense, given the math.
