Rename template references to variants

Where I previously thought that renaming HTML/CSS is more hassle than
it's worth, @mbertheau convinced me that to update a codebase, a general
search-and-replace is the best approach already and will catch any
HTML/CSS changes.

I also missed to deprecate the min_variant_price properties.

 Product structure
 ~~~~~~~~~~~~~~~~~
 
-Generally, backwards compatibility has been preserved. Two changes are
+Generally, backwards compatibility has been preserved. Those changes are
 unavoidable:
 
 * You now need to explicitly set product structure when creating a product;
   deprecation warning), but if you used the old related name in a query lookup
   (e.g. ``products.filter(variants__title='foo')``, you will have to change it
   to ``children``.
+* Template blocks and CSS classes have been renamed.
 
 The following methods and properties have been deprecated:
 
 * ``Strategy.select_variant_stockrecords`` - Use
   ``select_children_stockrecords`` instead.
 
+Furthermore, CSS classes and template blocks have been updated. Please follow
+the following renaming pattern:
+* ``variant-product`` becomes ``child-product``
+* ``product_variants`` becomes ``child_products``
+* ``variants`` becomes ``children``
+* ``variant`` becomes ``child``
