Title: Update vendor/PopPHPFramework/src/Pop/Loader/Autoloader.php

check if file exists; without this check this autoloader will
conflict with other autoloaders and that's not that uncommon.

Problem is that this autoloader tries to autoload a file which is
probably unavailable due to the fact that you have other libraries with
their own autoloaders and their own directory structure.

This will lead to fatal errors then.
