Each preference's name is used as a tag enclosing its value:
<ParagraphSpacing > 2
In some cases the data is multi-line:
<RecentFiles > <files > <file>Macintosh HD:Users:mwra:TBX:aTbRef24</file> </files></RecentFiles>
Preference 'Fontmap' data is also stored in multi-line form.
Colours are stored using 16-bit values (0-65535).
Some tags will be retained for compatibility with older versions of Tinderbox.
