Add electoral data.

Poll results: Downloaded from
    http://www.elections.ca/scripts/OVR2011/34/data_donnees/pollresults_resultatsbureau_canada.zip
and processed with
    recode ISO-8859-1..UTF-8 *.csv

Shapefiles: Downloaded from
    http://ftp2.cits.rncan.gc.ca/pub/geott/electoral/2011/pd308.2011.zip
Filenames changed:

*   Renamed Dictionnaire de données.doc to have UTF-8 encoded name.
*   Licence_ F.txt -> Licence_F.txt

Note that the area shapefiles are not added to the repo, because GitHub has
irritating file size limits.
Add simplified geometry.

Processed with
    ogr2ogr -progress -f "ESRI Shapefile" pd_a.simp.shp pd_a.shp -nlt POLYGON -simplify 1.0

Some checking in QGIS indicates that there don't seem to be any
major changes in the geometry, even for fine boundaries like in
city downtowns. Since the OGR simplification algorithm does not preserve
layer topology, it's best to be cautious -- but this still gives a 4x
reduction in geometry size.
Add scripts to import data into postgres.
Strip whitespace on import.
Add beginning of a script to create a cleaned data table.

The script is a hack at the moment.
