PHP Strict Errors

In the new php version 5.4.0, E_STRICT errors/warnings are activated by default. The plugin has some E_STRICT warnings, so they should be finally fixed. Some example errors:

Strict standards: Accessing static property ckeditor_wordpress::$plugin_path as non static in /wp-content/plugins/ckeditor-for-wordpress/ckeditor_class.php on line 24

Strict standards: Accessing static property ckeditor_wordpress::$plugin_path as non static in /wp-content/plugins/ckeditor-for-wordpress/ckeditor_class.php on line 32

Strict standards: Accessing static property ckeditor_wordpress::$default_options as non static in /wp-content/plugins/ckeditor-for-wordpress/ckeditor_class.php on line 41

You should activate E_STRICT and check for these errors to fix them.
