Incompatibility with Iways PaypalPlus

[schmengler]

The Iways PaypalPlus autoloader does not play well together with other third party autoloaders.

This results in error messages like

Warning: include(IntegerNet/Solr/Config/CategoryConfig.php): failed to open stream: No such file or directory in /var/www/app/code/community/Iways/PayPalPlus/Model/Autoloader.php on line 59
