This tries to encapsulate the management of the current dive and divecomputer in the selection code. The current dive is alreay set by setSelection(). Add a new parameter to also set the current divecomputer. If -1 is passed, then the current computer number is remained. This will allow us to audit the code. Because for now, the whole "current dive computer" thing seems to be ill-defined. This fixes a bug: the dive-computer number wasn't validated when making a new dive the current dive. The new code has some drawbacks though: when selecting a whole trip, the validation will be called for all dives in the trip and thus the dive computer number will depend on the dive with the lowest amount of dive computers in the trip. This will need to be fixed. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
