 The string format rules file (whose basename (i.e., filename minus the .plist
 extension) is given by the SA_DB_STRING_FORMAT_RULES_PLIST_NAME string) 
 contains values for variables that define the properties of legal die roll 
 strings, as well as certain variables that define the format of result strings.
 
 The file is organized as a dictionary contaning several sub-dictionaries. The
 valid keys (those for which values are present in the file), and the values
 that those keys may be expected to have, are listed below.
