Store the user's unit preferences in git storage

Save and load a usually unused copy of the preferences with the units that
were active the last time the dive list was saved to git storage (this
isn't used in XML files); storing the unit preferences in the data file is
usually pointless (that's a setting of the software, not a property of the
data), but it's a great hint of what the user might expect to see when
creating a backend service that visualizes the dive list without
Subsurface running - so this is basically a functionality for the core
library that Subsurface itself doesn't use but that another consumer of
the library (like an HTML exporter) will need.
