wp-mail.php: quoted printable encoding not decoding

[Staro]

When sending an email in this format:

Content-Type: text/plain; charset=ISO-8859-1
Content-Transfer-Encoding: quoted-printable

=E4=F6=FC
=C4=D6=DC
=DF

the message body will not be decoded. It should use the PHP function quoted_printable_decode(),
since many mobile phones can only send emails in this encoding.

I think this diff in attachment could fix it. (but don't know at which position exactly the conversion should take place)

Updated the already present patch to the current version of trunk.

(In [5188]) Add support to wp-mail.php for quoted-printable Content-Transfer-Encoding. Props Nazgul. fixes #2460

Note that function stripos is only available in PHP 5. You might want to change the condition on line 121 to strpos(strtolower($content_transfer_encoding), "quoted-printable") to ensure compatibility with providers still using PHP 4.

Also I think MIME headers are case insensitive too so the explode on line 116 might not always work.

And I'm still having the problem I posted in #3717.

stripos() was added in for compatibility already.
