Some column names have changed in the 20140527 dataset. :( :( :(
Add them to the alias list.
First attempt at 20140527 data load.
Combined precinct seperator changed from "," to ":" in 20140527 data load.
Combined precincts are now listed as one entry, rather than an entry per precinct in the 20140527 dataset.
In 20140527/generate.rb - Fixed legend from "Mar" to "May".

Added VotingPlaceLoader#explode_combined_precincts property to control
whether combined precincts should be exploded into multiple location
records.
