Implemented: Single, Global eztemplateautoload.php Include

With the acceptance of our previous pull request https://github.com/Open-Wide/OWSimpleOperator/pull/2 it no longer makes sense to force developers and users make static instances of eztemplateautoload.php operator autoload files since now the extension's provided autoload/eztemplateautoload.php file is now both dynamic and ini settings based.

Once merged these changes allow for a single global ezetemplateautoload.php file (already in place in the extension's autoload directory.

To create a custom operator you no longer need a custom class file + eztemplateautoload.php file + ini settings override; you only need your custom class file + ini settings override.

This is a big improvement to the current state of affairs. We hope you'll agree and accept this pull request.

These changes make using the OWSimpleOperator extension to create a custom operator class stored in a separate extension's class directory and activated via global ini settings override both painless and eZ to do!

Please let us know what you think!
