A 'navigation-to' CSP directive

Hello all,

Following the discussions at TPAC I have put together a document
proposal/explainer around a 'navigation-to' CSP directive.

This directive can help web authors control the top level navigations
allowed from their page and I have listed some scenarios where such a
directive could be used.

If you are interested, please have a look and feel free to leave comments.
