Four new features added: Content Security Policy, PageVisibility, Feature Queries and SVG fragment identifiers

The first three features submitted by GitHub contributors were added (actually several weeks ago) to Can I Use, these are:

- Content Security Policy: A method of defining what resources can be loaded from other domains and which cannot.

- PageVisibility: An API providing events and information relating to the visibility of the page to the user.

- CSS Feature queries (aka @supports): Method to use CSS properties based on the browser's support for certain property/properties.

Also added:

- SVG fragment identifiers: By setting a fragment on an SVG URL, it's possible to specify the part of the SVG image that appears (useful for sprites).
