Thread baseUri through with HTML jobs. (issue181068)

[mikes...@gmail.com]

Reviewers: jasvir,

Description:
Associate a base URI with HTML and CSS jobs so we can properly resolve
URIs.

This changes the way Jobs are constructed to carry around a base URI,
attaches that info to embedded content, and threads it into the
ResolveURIStage and InlineCSSImportsStage.
