Add the permission to change settings

I ran into this too. I have an "Editor" role and don't want them editing these settings. So, I modified the module and added a permission, so GTranslate does not show in the menu and is inaccessible even when accessed directly from the URL.

I just added a function;

function gtranslate_permission() {
  return array(
    'administer gtranslate' => array(
      'title' => t('Administer Gtranslate'),
      'description' => t('Allow users to edit the GTranslate settings.'),
    ),
  );
}

.. and in gtranslate_menu() I changed

'access arguments' => array('access administration pages'),

to:

'access arguments' => array('administer gtranslate'),

Patch following momentarily.

and here's the patch.

Thanks for the patch! Worked nicely.

Where paste the patch?
