[Plugin: Clean-Contact] chokes on apostrophes in blog title

The title of my blog has an apostrophe in it – D’Arcy Norman dot net – and the emails sent by clean-contact are being borked with this error message on my server:

A message that you sent contained one or more recipient addresses that were
incorrectly constructed:

  D'Arcy Norman dot net<contact@domain.com>: malformed address: ;Arcy
Norman dot net<contact@dom may not follow D&#039

(I altered the email address in the error message so I don’t get spammed)

I’ve modified line 124 in clean-contact.php to only send the $to_email value in $to, and it works fine now. Might be safer to add some scrubbing of encoded characters before sending the message.
