BUGFIX: opcache issue

I think it's possible to use it also with opcache enabled.

Following blocking should do the job.

```php
if (function_exists('opcache_reset')) {
    // >= PHP 5.5.0
    opcache_reset();
} elseif (function_exists('accelerator_reset')) {
    // < PHP 5.5 (previous ZendOptimizer+)
    accelerator_reset();
} elseif (function_exists('apc_clear_cache')) {
    // APC
    apc_clear_cache('filehits');
}
```
I moved it now to getAutoloaderConfig(), so the config is always refreshed!

The Module.php loading order is:
```sh
getAutoloaderConfig()
Init()
getConfig()
getServiceConfig()
getControllerConfig()
```
