Split up preference data structure definition into 'pref.h'

.. and rename the badly named 'output_units/input_units' variables.

We used to have this confusing thing where we had two different units
(input vs output) that *look* like they are mirror images, but in fact
"output_units" was the user units, and "input_units" are the XML parsing
units.

So this renames them to be clearer.  "output_units" is now just "units"
(it's the units a user would ever see), and "input_units" is now
"xml_parsing_units" and set by the XML file parsers to reflect the units
of the parsed file.
