Update from ayay.php library version 1.1.7

* Update session secret variable name
* Update getPublisherHTML()
* Update recordConversion()
* Update $fields URL encoding in doHttpsPost()


I tried the original bundle and was not working, rather than deciding to use the official library, I updated this one.  Does that sounds crazy?  xD  

Was going to add another commit for fixing the coding standards wtih https://github.com/fabpot/PHP-CS-Fixer   Thoughts?

Thanks!
