Blankie not setting frame-ancestors by default #45
Description
Most CSP libraries, like Helmet for example, set: frame-ancestors 'self'; by default. Can you add that to the default setting for Blankie? And make it clear how to turn that off/change it, if that default isn't desired? I'm using Blankie, with Hapi, and @hapi/scooter if that matters.
I also find it interesting that the default-src tag value is 'none' instead of 'self', which is what I've seen all other default CSP settings to use. Why is 'none' the default-src default for Blankie?
