I think refering to the template as relative to a package is better than 
assuming things about the places packages have been installed.
How about this:

    <browser:page
      for=".interfaces.IReSTDocument"
      name="preview.html"
      menu="zmi_views"
      title="Preview"
      template_package="zope.app.browser.content"
      template="preview.pt"
      permission="zope.ManageContent"
      />

An alternative is to introduce a package:file syntax:

    <browser:page
      for=".interfaces.IReSTDocument"
      name="preview.html"
      menu="zmi_views"
      title="Preview"
      template="zope.app.browser.content:preview.pt"
      permission="zope.ManageContent"
      />

This latter syntax would work for the icon directive too, I guess.
