I promoted the addresses from comma-separated values in addr:housenumber to distinct address points to give them geographical context (previously, you couldn't reliably tell which side of the building was which number) and also straighten out the street name associations (for example, 4465 South Robberson Avenue and 238 West Camino Drive are connected units with different associated streets; previously, you'd've had to use balanced delimiters in addr:street...ick).

I also re-suffixed the "Camino" names from "Street" to "Drive" based on signage seen in Bing Streetside imagery.

Done in changeset 161116886.

(I'm not from Springfield, so please let me know if I fumbled a local convention.)
