Add ev: name space

I needed RSS for event listings.

http://web.resource.org/rss/1.0/modules/event

I simply added these lines into 'views_rss_core.module' after line 178:

// add ev: name space items for events 
  $elements['ev:location'] = array(
    'description' => t('Event takes place at.'),
    'help' => 'http://purl.org/rss/1.0/modules/event/',
  );
  $elements['ev:organizer'] = array(
    'description' => t('Events is organized by.'),
    'help' => 'http://purl.org/rss/1.0/modules/event/',
  );
  $elements['ev:type'] = array(
    'description' => t('Type of event.'),
    'help' => 'http://purl.org/rss/1.0/modules/event/',
  );
  $elements['ev:startdate'] = array(
    'description' => t('Event begins at.'),
    'help' => 'http://purl.org/rss/1.0/modules/event/',
  );
  $elements['ev:enddate'] = array(
    'description' => t('Events ends at.'),
    'help' => 'http://purl.org/rss/1.0/modules/event/',
  );

For now, as a newbie, I don't have time for creating a module, take over or wait.
