little fix for translation taxonomy_breadcrumb.module

hello,

I'm using the taxonomy_breadcrumb module,
and I got a little error by generating the pot file for translations, by using the classic drupal extractor.php file.

the error was at the line 211 of taxonomy_breadcrumb.module file.
this, to me, should be better by getting out the implode() function from the t() function, as below:

  t('Enter a list of node... enabled:') .'<ul><li>' .implode($node_bases,'</li><li>') .'</li></ul></p>',

thanks for this contrib,

Piero Trono

P.S:: in attachment the pot file
