Italian translation

Only a little thanks for the module.

Note: there is a little problem about translation(s): the array $hide_opts in last function (taxonomy_delegate_settings_form) use values not translatable (fixed in PHP, without t()).
The terms for labels are "globals", so with:

$hide_opts = array(
    'parent' => t('Parent'),
    'synonyms' => t('Synonyms'),
    'weight' => t('Weight'),
    'relations' => t('Related terms'),
    );

the translation is done... without additions.

Ciao;
Matteo
