desktop UI: create the UI components for editing the salinity.

The user may modify the salinity by selecting a water type from the combobox.
The new datum does not replace the existing salinity value but is stored in a
separate variable within the dive structure. If the dc-based salinity is
overwritten, there is an exclamation mark next to the modified salinity value
to indicate that the salinity has been overwritten. The dc-derived salinity can
always be recovered by selecting the "use dc" option in the combobox.
