Stylesheets from <link rel="import"> are not reloaded

[sgtpep]

Let's assume that I have index.html:

<link rel="import" href="component.html">

which contains:

<link rel="stylesheet" href="component.css">

When component.css has changed, livereload servers (like tiny-lr) signals livereload-js to reload component.css by updating the tag, which is not present on index.html.

If I get it right, this is related to Web Components/Polymer.
In any case, it is related to #32, where livereload could support nested documents.
