Text can only only inside paragraphs and inlines. This patch makes it
so we stop putting such text nodes in the render tree at all if their
parent is not a paragraph or an inline.
This is the final step in making it so that we don't create anonymous
renderers, which fixes a crash in the new custom layout code.

Per the spec in modules.md the exports property should default to an
empty object. We lazy allocate it so that modules that just replace it
don't create the empty object and then throw it away.

This CL adds basic support for the <import> elements. We're using the same imports
machinery as <link rel="import">, which simplifies this patch substantially.
Currently we support both <link rel="import"> and <import>. Once this CL lands, I'll
update all the existing modules and then we can drop support for
<link rel="import">.
