Mime: encode comma

[glensc]

this does solve GenericHeader::toString + Header\AbstractAddressList::fromString problem
reported here: zendframework/zend-mail#146

Interestingly, this causes existing expectations to fail; please review the travis logs. If the existing tests are now incorrect (as the proposed change would encode commas), then please update the unit tests. It the existing tests are correct, then your patch needs updating.

Thanks!

yes, obviously it changes encoding result.

if you accept the change, i can update tests to use updated encoding result.
see details in referred PR zendframework/zend-mail#146

there's only one test failing:

1) ZendTest\Mime\MimeTest::testEncodeMailHeaderQuotedPrintable with data set #3 ('Alle meine Entchen schwimmen ... Höh!', 'UTF-8', '=?UTF-8?Q?Alle=20meine=20Entc...B6h!?=')
Failed asserting that two strings are equal.

updating it, is trivial, so done
