Bug (and fix): Broken "Search Engine Referrers" count

I found that the shortcode for displaying the search engine referral count wasn’t working, and I found some typos in the plugin code that caused the break. Making the changes below fixed the problem, and the count now displays properly!

The first one is in /wp-statistics/shortcode.php, line 31:
$result = wp_statistics_searchengine($attr['provider']);
should be
$result = wp_statistics_searchengine($atts['provider']);
($attr > $atts)

The second is in /wp-statistics/includes/functions/functions.php, line 315:
$search_query = wp_statistics_Searchengine_query($search_engine);
should be
$search_query = wp_statistics_searchengine_query($search_engine);
(Searchengine > searchengine)
