Conflicts:
	snapshot.js
added a stylesheet
removed spurious ~ file
re-generated from upstream WHATWG
Added paragraph to intro

Added para talking about relationship to rfc 3986 and rfc 3987.
clarified that the added para to the intro is w3c
added w3c-specific text document

This is a (hopefully temporary) document that will contain snippets
which are to be included in the w3c version of the spec but are not
appropriate to be pushed back to the whatwg version.
