Bug Discovered

Hello,

the regex in this plugin cannot handle underscores in the video id e.g.

http://www.youtube.com/watch?feature=player_embedded&v=B9sBlmY_iME

it strips the _ resulting in a malformed id e.g.

B9sBlmY

to fix this update the regex expression in the youtube function at line 202 from

if (preg_match('/^http:\/\/.*(v=([-0-9a-zA-Z]*)).*$/', $attribute, $matches))

to

if (preg_match('/^http:\/\/.*(v=([-0-9a-zA-Z_]*)).*$/', $attribute, $matches))
