Working again: Fix for the preg_replace problem

SEO Auto Links is IMHO the most effective autolinking plugin out there. Unfortunately, it won’t work under PHP 7. I had a look at the code regarding the preg_replace warning and came to this fix by replacing the deprecated preg_replace function and the /e modifier with the preg_replace_callback function.

In seo-auto-links.php Line 79:

Replace

$text = preg_replace('%(<h.*?>)(.*?)(</h.*?>)%sie', "'\\1'.SEOAutoInSpecChar('\\2').'\\3'", $text);

with

$text = preg_replace_callback('%(<h.*?>)(.*?)(</h.*?>)%si',
   function($m) { 
      return $m[1].SEOAutoInSpecChar($m[2]).$m[3];
    },
       $text
    );

In seo-auto-links.php Line 258:

Replace

text = preg_replace('%(<h.*?>)(.*?)(</h.*?>)%sie', "'\\1'.SEOAutoReSpecChar('\\2').'\\3'", $text);

with

$text = preg_replace_callback('%(<h.*?>)(.*?)(</h.*?>)%si',
      function($m) { 
         return $m[1].SEOAutoReSpecChar($m[2]).$m[3];
       },
      $text
    );

After this modification, it should work fine again.
