Title: Adding checks for interesting `iframe` attributes.

Good morning, lovely Modernizr folks. This patch adds support for a few interesting `iframe` attributes:

* @sandbox enables granular restriction of the permissions with which
framed content is allowed to run.

* @seamless renders `iframe` elements as though they were part of the
containing document. CSS bleeds through, and links open in the parent
window, for instance.

* @srcdoc provides the content that the frame ought to display.

All three are implemented in WebKit, and are specified in the ["The iframe
element" section of the WHATWG HTML living standard][1].

Thanks!
