i18n: Extended default node language selection

I developed a module that added the possibility to set a fixed or dynamic default language and the possibility to remove 'Language neutral' from the language select box and adds a '- Please choose -' option as first in the select box. (Language select). These features were talked about by other users (http://drupal.org/node/198355 http://drupal.org/node/250891 http://drupal.org/node/527862).
The first new version of i18n included part of this functionality (to remove 'Language neutral'). So I created a patch for i18n to add the extended default node language selection.
After applying this patch the checkbox 'Set current language as default' is replaced with a select box 'Select default language'. From this select box you can choose a dynamic or fixed default language.

• Dynamic:
  • User language = The language of the user creating the node as set at 'My account >> Edit'
  • Interface language = The language of the interface the user is viewing (e.g. www.example.com/node/add/page -> English, www.example.com/nl/node/add/page -> Dutch)
• Fixed
  • Any of the languages enabled for the site
  • No default language = Sets the dropdown to '- Please choose -'
  • Language neutral = Falls back to No default language if Disable Language neutral is selected

I hope I made the patch correctly.
