Now that the reference is split into backend/frontend, it makes more
sense to have the assets page into the frontend section.

The terminology did not really make sense for a lot of these sub pages.
This change should have been done long ago, but was probably delayed
because some people in Odoo call the web client the "backend", which is
really misleading.
This commit also renames the title "Reference Guides" to "Reference",
since this section does not contain any guides anyway.
