When merging planned dives keep all cylinders

Browse source 
When merging a real dive with a planned dive (for comparison),
we should not try to be clever in merging similar cylinders,
rather keep the union of both cylinder sets as the two versions
of the dive might differ in exctly which gas and how much of it
was used.

Increase MAX_CYLINDERS to 20 to make room for this.
