PL Added 4/4-4/11 data

(Dario had downloaded the data and put in in the intermediate

Updated auction link to be more specific
Changed link and text for current list of covered entitites so that we
don't have to deal with the constantly-changing URL for the excel that
CARB maintains.
Merge remote-tracking branch 'origin/master' into gh-pages
