Fix the social-and-tools box on the home page

This fixes a problem introduced in 705a5d04e1b7b65ca49ee71a4d7f97,
which changed the layout of the social media box on object pages,
but broke its layout on the front page.

Thanks to Jedidiah Broadbent (@Jedidiah) for spotting that a
"float: right" was missing for .social-and-tools on the front page.
Add a script to convert PDFs to one-PNG-per-page

This useful for converting the party list PDFs into a
more workable format.
Add a helper script to deskew and unpaper scanned pages
Update the link to the Presidential Aspirants page
Add wards to the Places menu and reorder the menu

It makes more sense to me to go from the largest areas to
the smallest going down the menu.
Add a script to import ward Places and set their parent constituency Place

This script requires a CSV version of the table contained in the
document "Final Constituencies and Wards Description.pdf", which
was downloaded from http://iebc.or.ke/

This was converted to a CSV file by Jedidiah using Adobe Pro's
"Save as .xlsx" option, and me opening that in LibreOffice and
exporting as CSV.

As a quick fix, set disqus_identifier to undefined in all cases

This was requested by @evdb while on holiday, to fix the
display of comments.  Apparently contrary to Disqus's
documentation, the path will be disregarded if
disqus_identifier is set.  There's some relevant discussion
here:

Add a datamigration to set 'place' for Aspirant President positions

This is important so that we can deal with all aspirants connected
with a place in a consistent way - we walk up the hierarchy of
place to the country level, so it's natural to include presidential
aspirants at that level in the same way.  This datamigration only
makes this change if the COUNTRY_APP is set to 'kenya'.
