ext_smtp.py sends empty (wrong) email addresses in server dialog

[TomFreudenberg]

The current code will send empty addresses as RCPT TO: dialog <> which cause errors e.g. on mailersend service.

cement/cement/ext/ext_smtp.py

Lines 135 to 136 in ea32057

	msg['Cc'] = ', '.join(params['cc'])
	msg['Bcc'] = ', '.join(params['bcc'])

Code should be:

        if params['cc']:
            msg['Cc'] = ', '.join(params['cc'])
        if params['bcc']:
            msg['Bcc'] = ', '.join(params['bcc'])

If you like I can make a PR for both tickets

Cheers
Tom
