Riven NAME resources

They contain a list of strings with an associated value, and their purpose is to store names for variables, cards, hotspots and other entities. They have the following structure:

unsigned short	field_count
unsigned short	string_offsets[field_count]
unsigned short	values[field_count]
char*	strings strings is a list of zero-terminated strings. You can access string n by looking at string_offsets[n], which is the offset starting from strings (not from the beginning of resource data). The meaning of values[] is not yet known, but it seem to go from 0 to field_count-1 (not in sequential order). This field apparently has no function (the record index is important, instead). In saved games there's only one NAME resource; it stores the name of each variable in the VARS (the record index in the NAME matches the one in the VARS). In data files there are more NAMEs: ID 1 stores card names, ID 2 hotspot names, ID 3 external command names and ID 4 variable names. In this case, the record index is equal to the number used in script commands to access the variable. Finally, ID 5 stores stack names and it's used by command 27 to change island.
