Changes on 11-19-16:

• Fixed the couriering help file to correct a company location being on Miriani rather than Pax.
• Added two new levels of improved diving oxygen tanks, high capacity (1.5 hours) and super capacity (2.0 hours).
• Included oxygen tank refilling in the 5 second water pulse that handles everything else having to do with diving. Consequently, this fixes a few oddities, including but not limited to tanks not being refilled if your ship was powered down for an extended period of time.
