Dive list: fix crash on dive import

Browse source 
In commit 8c2383b495 dive merging was
changed to not modify the original dive. On import, dives were then
merged and the original deleted. The merge_weightsystem_info() was
not adapted accordingly (deep copy of string instead of pointer),
leading to a use-after-free crash.

Resolve this by doing a deep copy.
