Partial node form and languages

This patch works for me...

The patch in #2 works fine.

@Devin Carlson: the bundle label has not been translatable for me with Internationalization installed.
The node-types were already translated and show up correct on node creation page.
Personally I would prefer to create the string in total first and than run it to t(). The current solution:
'Create a @bundle'
will create
'Create a document'
'Create a event' ... which should be 'Create an event'
running the complete string to t() will give us - at least in the other languages - the chance to display wording correct without constructs like 'Create a(n) document','Create a(n) event'.

Next things need to be fixed...

In:
commons_posts.module
commons_polls.module
commons_q_a.module
commons_wikis.module

Creation of partial node form is hard coded to (f.e. posts)

function commons_posts_form_commons_bw_partial_node_form_alter(&$form, &$form_state) {
  if (empty($form['#entity']) || $form['#entity']->type != 'post') {
    return;
  }

  $form['body'][LANGUAGE_NONE][0]['#title_display'] = 'invisible';
  $form['body'][LANGUAGE_NONE][0]['#required'] = TRUE;
  $form['body'][LANGUAGE_NONE][0]['#placeholder'] = t("What's on your mind?");
  $form['body'][LANGUAGE_NONE][0]['#resizable'] = FALSE;
...

function commons_posts_form_commons_bw_partial_node_form_after_build($form) {
  $form['body'][LANGUAGE_NONE][0]['#pre_render'] = array();
  $form['body'][LANGUAGE_NONE][0]['format']['#access'] = FALSE;
  $form['body'][LANGUAGE_NONE][0]['value']['#rows'] = 3;

  return $form;
}

The result, all these nice things done here do not work.

Based on the suggestion in #2 to select a language or "LANGUAGE_NONE" I added a small function:

function community_box_language($type) {
  global $language;
  if (module_exists('locale')) {
    if (locale_multilingual_node_type($type)) {
      return $language->language;
    }
    else {
      return language_default();
    }
  }
  else {
    return LANGUAGE_NONE;
  }
}

And replaced all:

$form['body'][LANGUAGE_NONE]

with:

$form['body'][community_box_language($form['#entity']->type)]

in the files mentioned above.

After that, everything works like in a fresh installed 3.3.
