Commit e219bc70f8 ("Refactor dctype -> divemode") introduced a few issues.
For one thing it causes a warning about incorrect use of zorder - I don't see
why this would be needed here, so I simply removed it.
Secondly, it adds a new, automatically named layout element that therefore gets
handled by our "consistent margin" code which creates a messy layout for the
Dive Notes tab. This patch gives that horizontal layout a useful name and adds
it to the list of "zero margin" layouts. Signed-off-by: Dirk Hohndel
