Some more testing revealed a problem with ckanapi and CKAN running
under Apache: Apache may not pass through the 'Authorization' header,
so I've switched to the 'X-CKAN-API-Key' header.  If you were getting
NotAuthorized errors this fix might help you.

Here's a simple package_create with extras using ckanapi:

  import ckanapi
  dev = ckanapi.RemoteCKAN('http://my-dev-ckan', api_key='fd7bd...')
  dev.action.package_create(
     name='simple-test',
     extras=[{'key': 'custom-field', 'value': 'extended data'}])

where the last line is the same as:

  dev.call_action('package_create', dict(
     name='simple-test',
     extras=[{'key': 'custom-field', 'value': 'extended data'}]))
