All civicrm drupal modules should return if civicrm can't be initialized

In the main civicrm.module, every drupal hook uses the following logic at the start of the hook.

if ( ! civicrm_initialize( ) )

{ return; }

This is not so for all the other drupal integration modules, which do call civicrm_initialize(), but do not return on a failue. So, if for some reason civicrm couldn't be initialized, the user ends up with a fatal php error something along the lines of

Fatal error: require_once() [function.require]: Failed opening required 'CRM/Core/Config.php' (include_path='.:/home/tom/workspace/concern6/sites/concernfast.org/modules/civicrm:/home/tom/workspace/concern6/sites/example.com/modules/civicrm/packages:.:/usr/share/php:/usr/share/pear') in /home/tom/workspace/concern6/sites/example.com/modules/contrib/civicrm/drupal/modules/views/civicrm.views.inc on line 49

I think all the drupal integration code should gracefully return if civicrm couldn't be initialised, just like the main civicrm module.
