Refactor|IdTech1Converter|MapInfoTranslator: Track custom status of MAPINFO data, split output
Partition the translated definitions into two data sets, according to whether the source MAPINFO data is "custom" (from an add-on). By separating the data we can continue to track the custom status for individual definitions, should multiple MAPINFO data be merged from multiple sources.
