Fix issues and run scraper

[zackgomez]

NOTE: It looks like the auto formatter ran, if you care to merge and don't want that change, I can look into auto formatting with your settings.

Three fixes

1. npm upgrade
2. rename types.d.ts to types.ts and import as necessary
3. fill in empty properties array after scraping for classes which inherit but have no properties themselves
