there was _class not found_ error with old verison.

to solve this I was forced to change this line of code or to change the config from
```php
'sass' => array(
	...
	'sassPathAlias' => 'application.extensions.phpsass',
),
```
to
```php
'sass' => array(
	...
	'sassPathAlias' => 'application.extensions.phpsass.SassParser',
),
```

as variable name is _sassPathAlias_ (not _sassClassAlias_), I decided to change this import line and do not change the config.
