Small change makes # searchen work with scandinavian characters etc.

I noticed that the hashtags did’nt work with special swedish characters in UTF-8. So I changed something in model/twitter-search.php to make it work.
line 74 was:
$content = preg_replace( '/(^|\s)#(\w*[a-z_]+\w*)/i', '\1<a href="http://search.twitter.com/search?q=%23\2">#\2</a>', $content );

changed to:
$content = preg_replace( '/(^|\s)#(\w*[a-z_üÀ-ÖØ-öø-ÿ]+\w*)/i', '\1<a href="https://twitter.com/search?q=%23\2">#\2</a>', $content );
