/*!
\brief This saves all family names and styles to the file specified in
ServerConfig.h as SERVER_FONT_LIST as a flattened BMessage.
This operation is not done very often because the access to disk adds a significant
performance hit.
The format for storage consists of two things: an array of strings with the name 'family'
and a number of small string arrays which have the name of the font family. These are
the style lists.
Additionally, any fonts which have bitmap strikes contained in them or any fonts which
are fixed-width are named in the arrays 'tuned' and 'fixed'.
