 * Revision 2.3  2005/11/24 08:46:10  Goober5000
 * * cleaned up mission_do_departure
 *   * fixed a hidden crash (array index being -1; would only
 * be triggered for ships w/o subspace drives under certain conditions)
 *   * removed finding a new fighterbay target because it might screw up missions
 *   * improved clarity, code flow, and readability :)
 * * added custom AI flag for disabling warpouts if navigation subsystem fails
