Added template for displaying tree node page #4657
Call rec_name directly instead of method call
Use category as breadcrumb on product page
Support tree_node and category for navigation #4721

product.tree_node is a far better hierarchial classification system
than product.category. Despite this, some sites may want to stay simple
and use category (which they might already use) for navigation.

This patch separates the rendering of top site navigation into _helpers
as two macros, for category and tree_node. Depending on the root navigation
model specified for the current website, the appropriate one is used

Refactoring of category and product pages
Use the new description getter function

Since nereid-catalog version 3.0.5.0 it is possible
to set a description for the template and all the variants
could resuse that.

This getter function moves the logic of getting description
to a method in the model.
