Incorporate patrons bulk data

[waldoj]

Right now we're scraping copatron data with copatrons.php. But this is available as bulk data now, in Sponsors.csv on the FTP site. Switch to this data source, instead. It's real easy—it looks like this:

"MEMBER_NAME","MEMBER_ID","BILL_NUMBER","PATRON_TYPE"
"Tony O. Wilt                  ","H0231","HB0001","1001" - Chief Patron
"Richard P. Bell               ","H0211","HB0002","1001" - Chief Patron
"R. Steven Landes              ","H0104","HB0003","1001" - Chief Patron
"Glen H. Sturtevant, Jr.       ","S0099","HB0003","2999" - Co-Patron
"Michael P. Mullin             ","H0286","HB0004","1001" - Chief Patron
