Allow CCK Formatter modules to define expected gis inputs ( point, linestring, etc) via hook_field_formatter_info()

1. A module declares CCK formatters using the usual syntax, but includes the
   "gis input" key:

   function geo_field_formatter_info(
     return array(
       'default' => array(
         'label' => t('Well Known Text'),
         'field types' => $field_types,
         'gis types' => array('point', 'linestring', 'polygon'),
         'gis input' => 'wkt',
       ),
       'lat' => array(
         'label' => t('Latitude'),
         'field types' => $field_types,
         'gis types' => array('point'),
         'gis input' => 'array',
       ),
     );
   }
2. Geo's CCK modules retrieve data in WKB format
3. On nodeapi:view, geo performs an on-the-fly conversion from WKB to the
   expected input format ( e.g. wkt, array, and so-on)

- Implemented this for all included formatters.
