Planner: Properly initialize salinity
When the dive has no explicity salinity, our conversion between pressure and depth assumed salt water. Make this explicity by using the corresponding macro. When the planner starts and no salinity is set explicity, set the water type chooser to salt water to reflect our default assumption. Signed-off-by: Robert C. Helling <helling@atdotde.de>
