desktop: add tab-widget for dive computer names

If we want to include dive computer names in the undo system,
there should be visual feedback on undo/redo.

This would mean opening the divecomputer dialog, which would
appear quite strange. Therefore, add a tab. This is not ideal,
but consistent with the dive site tab, which probably shouldn't
be there either. In the future, the UI needs some rethinking.
