devices: connect DiveComputerModel to undo-command

Instead of modifying the device table directly, call the undo
commands. Moreover, don't keep our own copy in the mode - show
the original version. Connect to the appropriate signals.

This means that the calls from the DiveComputerManagement
dialog have to be removed, since this mode of editing is
not supported. The whole dialog will be removed in a future
commit.
