Ability to translate/rename source string within the table

My client wanted the ability to translate the source string inside the table. I see no reason why that shouldn't be possible so I threw together a quick hack for him.

I changed this at line 40:

$form['source'] = array(
  '#type' => 'markup',
  '#value' => check_plain($source->source),
);

to this:

$form['source'] = array(
  '#type' => 'textfield',
  '#default_value' => check_plain($source->source),
  '#size' => 35,
  '#maxlength' => NULL,
);

And I added the part between the #### Hack comments inside this function

/**
 * Submit handler for the translation table.
 */
function translation_table_submit_translations($form, &$form_state) {
  switch ($form_state['clicked_button']['#id']) {
    case 'edit-submit':
      $language_list = locale_language_list('language', TRUE);
      db_query("UPDATE {locales_target} SET translation = '%s' WHERE lid = %d AND language = '%s'", $translation, $lid, $lang_code);
      foreach ($form_state['values']['strings'] as $lid => $values) {
######### Start Hack
        $tid = str_replace('term:', '', $values['location']);
        $tid = str_replace(':name', '', $tid);
        $term = (array)taxonomy_get_term($tid);
        if ($values['source'] != $term['name']) {
          $term['name'] = $values['source'];
          $taxonomy_term_form_state = array();
          $taxonomy_term_form_state['values']['tid'] = $tid;
          $taxonomy_term_form_state['values']['name'] = $values['source'];
          
          //include the file containing the required functions
          module_load_include('inc', 'taxonomy', 'taxonomy.admin');

          drupal_execute('taxonomy_form_term', $taxonomy_term_form_state, taxonomy_vocabulary_load($term['vid']), $term);
        }
######### End Hack
        foreach ($values as $lang_code => $translation) {
          if (in_array($lang_code, $language_list)) {
            _translation_table_update_translation($lid, $lang_code, $translation);
          }
        }
      }
      break;
  }
}

I don't know how to create a patch, but I'm posting it here for you or anyone else to take a look at if you're interested. :)

I'm a pretty poor programmer so some things are probably pretty hacky, but it works and me and my client is happy. :D

It sets an error message if you try to submit the form with an empty source string field and all the set_messages it spits out if you edit a lot of fields at once can be a bit annoying, but those things can probably be fixed rather easily. I don't want my client to delete terms by emptying the field so that's actually fine for my use.

If you spot some major problems with my approach then please let me know because this code is in use now. :)
