Description:
------------
On line 492 of mimeDecode.php the first space of the header value is
removed. However, I encounter mails that have an empty $hdr_value so
checking $hdr_value[0] causes a 'Uninitialized string offset: 0' notice
in PHP 7. The addition of a simple '!empty($hdr_value) &&  ' would fix
this.

Test script:
---------------
<?php
error_reporting(E_ALL | E_NOTICE);
require_once 'Mail/mimeDecode.php';

$mail = 'X-TestHeader:

Testbody';

$decoder = new Mail_mimeDecode($mail);
$decoder->decode([]);


Expected result:
----------------
No notices

Actual result:
--------------
The notice mentioned above.
