Title: Comment the href attribute example rule to emphasise how arbitrary content can be sourced from a browser view

Laurence mentioned in a [mailing list thread](http://plone.293351.n2.nabble.com/Simplifying-the-schema-story-tp7558876p7558981.html) that an href attribute on rules lets you "include elements from subrequests into your final page (no need to write viewlets, just write a utility view for your theme)". Such a handy technique deserves emphasis in the `plone.app.theming` user guide.

Added a comment to the href attribute example rule to make clearer that content can be sourced from a browser view.
