Add a skeleton South Africa application
Add a boundary import script for South Africa

This is designed for data from http://www.demarcation.org.za/

This should probably be rewritten, as described in the
comment at the top of the file, to use a different set of
shapefiles and just load them using mapit_import - this
would cut down the code a lot.  However, I only realized
the shapefiles at each level were available when this
script was virtually finished, so it doesn't seem worth
rewriting it now.
Deal with the "Governmental" OrganisationKind not existing
Remember to add the generated CSS for South Africa
Municipality names are actually encoded with ISO-8859 rather than UTF-8
Add the SCSS source for the South African CSS
Add an alias so the MapIt static assets can be found
Try to generate the MapIt CSS from prepare_environment.bash

Arguably this should be done from MapIt's setup.py, instead,
but this deals with the issue for Mzalendo for the moment.
Simplify the South African boundary import script

Hopefully using all four shapefiles instead of just
wards + districts will produce better data, and has the
advantage that we have stable identifiers for local
munipalities and provinces too.

This version depends on having the --name_suffix_field
option in MapIt, in order to construct unique ward
names.
