Panels 3 integration for Content Taxonomy

Here's the code. To include in Content Taxonomy, proceed as follows:

1) Create the directory includes/panels/relationships inside the content_taxonomy module directory.

2) Copy to the new subdirectory the attached file terms_from_field.inc

3) Edit content_taxonomy.module and append the following code:

/**
 * Implementation of hook_ctools_plugin_directory().
 */
function content_taxonomy_ctools_plugin_directory($module, $plugin) {
  if ($module == 'ctools' && $plugin == 'relationships') {
    return 'includes/panels/' . $plugin;
  }
}

That's it.
