qthelper: add means to retreive weight and cylinder info in Dive

The Dive helper class only picks the first cylinder and the total
weight. This patch adds the option to dump the cylinders and weights
as formatted lists (via cylinders() and weights()) or to retrieve
a specific cylinder or weight via (cylinder(index) and weight(index)).

Each cylinder and weight string contains detailed information:
cylinder:
- desc.
- pressure (+start/end)
- gasmix
- etc...
weight:
- desc.
- weight (in units e.g. kg)

If no description is found for a cylinder or weight the contents
for this particular unit is filled with EMPTY_DIVE_STRING ("--").
