Fix wrong handling of Dive Table, and revert some wrong changes.

This patch just reverts some wrong changes that I'v done on a
past commit ( sorry ) and correctly handles the selectDive,
by using a IDX instead of the dive pointer, as dirk told me
it's extremely error-prone since the pointer can change.
