Geocoding, GeoRSS, and KML for Plone 3

I've made the necessary configuration changes so that PleiadesGeocoder 1.0b2 works with Plone 2.5 or Plone 3.0. To deploy PleiadesGeocoder in a Plone 3 buildout, add geopy and simplejson to the buildout eggs in buildout.cfg:

[buildout]
...
eggs =
    elementtree
    geopy
    simplejson

and add the PleiadesGeocoder tarball to the list of product distro URLs:

...
[productdistros]
recipe = plone.recipe.distros
urls =
    http://gispython.org/downloads/zope/PleiadesGeocoder-1.0b2.tar.gz
...

Then run the buildout script again to update.

Thanks to David Siedband for the initial testing on Plone 3.
