This fixes a theoretical issue with database interaction. Because the fields in the database are signed 64-bit integers, it's theoretically possible to overflow them if we're using unsigned 64-bit integers in the application code.
uint64 fields get marshalled into json by protobuf as strings, so we have to tell the json parser to look for strings when unmarshalling.
