Scrape and populate old Events and EventTeams (2002 and prior)

We can scrape team pages for Events and event attendance (EventTeam) from events that are pre-2003.

Notes:
- This will be slow and is supposed to be used as a one-time-only run. As an optimization, it only scrapes FIRST team pages for teams <= 999 (these teams participated in events from 2002 and prior).
- Championship divisions started in 2001, which means we don't have the proper information to create Events and EventTeams for 2001 and 2002 Championships. As a result, this doesn't create Events and EventTeams for 2001 and 2002 champs.
