Remove <base> tag from rendered HTML
Add tests for PLIP 13705
We need to use absolute url since we don't have <base>
Do not use kss_field_decorator_view.

This is defined in Products.Archetypes, which is no longer a dependency.
We might want to rewrite this or move it to plone.app.kss,
Note that the main_template in CMFPlone and all the themes use it.
