The custom TableView widget saves the table width on destruction.
For that, it uses the "objectName()". Since the table of the
DiveComputerTab was simply called "table" in the UI file, the
widths were saved in that generic section. To avoid future
name-conflicts, rename the widget to "devices".

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.
