Accepts Internationalized Domain Name everywhere PHPMailler expects
email addresses (To, CC, BCC, Reply-To, From, Sender and
ConfirmReadingTo).
Requires PHP >= 5.3 with "intl" extension installed and "mbstring"
extension enabled. Earlier versions don't see a change, i.e. specifying
an address with IDN still fails validation.
Follow-up to PR #516. Ran test/phpmailerTest.php
Other changes:
- From, Sender and ConfirmReadingTo addresses are now validated in
send(). Previously, only From and Sender addresses would be validated
only if specified via the setFrom() method. ConfirmReadingTo was never
validated.
- Half language strings for the 'invalid_address' message used colon at
the end and half didn't. Harmonized messages to always include colon,
and not add a second one with PHP code.
