Dominik Schilling 598907559c WP_Widget: Introduce is_preview() method.
With the Widget Customizer it's possible that previewed widgets can leak data outside of Customizer, when the widget uses the cache API.
The Customizer calls the regular update callback which should already refresh the cache. Since cache additions aren't blocked yet the cache can be filled with preview data.
To prevent this issue `WP_Widget::is_preview()` will return true, when `$wp_customize->is_preview()` returns true. If `is_preview()` is true, cache additions are suspended via `wp_suspend_cache_addition()`. Make sure your object cache drop-in has implemented `wp_suspend_cache_addition()`.

`is_preview()` can/should also be used inside `WP_Widget::widget()`, see WP_Widget_Recent_Posts or WP_Widget_Recent_Comments for examples.
