[PATCH 2/2] Ticket #831 Fix

[Willem Ferguson]

Dirk and Tomaz,
How easy would it be to implement reordering the cylinders in the
equipment tab after they have been copy-and- pasted from another dive,
that is, without having to delete and re-type all the information for a
cylinder? The present setup is not very user-friendly for divers using
more than one cylinder because a cylinder is always added at the end of
the list. So if cylinder position is important, one often has to erase
all but one of the existing cylinders and manually re-do the remaining
cylinders.
Kind regards,
willem
