Notice of invalid key sometimes being thrown

[ddelrio1986]

The cleaner_gallery_get_setting function will sometimes throw a notice if you're trying to access a $option that is not found in the $settings array returned from the get_option function.

In cleaner_gallery_get_setting(), I need to do something like this:

$settings = get_option( 'cleaner_gallery_settings', cleaner_gallery_default_settings() );

$settings = wp_parse_args( $settings, cleaner_gallery_default_settings() );
