Add the possibility to no store a placeholders for video (all service: YouTube, Vimeo, ecc) and use just the standard image.

Add the possibility to have a settings that allow to disable placeholders storage, delete all stored placeholders and use the standard one instead.

Currently for have this results I need remove all content inside wordpressmainfolder/wp-content/uploads/complianz/placeholders/ than remove all write permission to the folder placeholders.

If I don't do this, placeholders are still saved and still exist on my hosting.
Also the guide wordpressmainfolder/wp-content/uploads/complianz/placeholders/ was not working for me.
