fix send_email function for multi-part addresses

Browse Source 
The send_email function wasn't successfully parsing ; or , separated email address lists. I simplified it's processing.

While I was at it I removed the "valid email" check from email_test.php because that step is already being done in the send_email function that is called and it safely returns the appropriate error. I would have had to rewrite that function to handle the multiple email lists otherwise.
