Add depth colum to cylinder model

To make the planner work this adds a new column to the Cylinder widget
(depth - for the depth at which we want to change to a certain gas
during deco).

This also tries to hide that column in the equipment view and hide the
start/end pressure columns in the planner view. Oddly that fails :-(
