fix(apis_entities,core): add templatetag for generating entitymenu

This introduces `entities_verbose_name_plural_listview_url` templatetag,
which returns all entities verbose names together with their list uri,
sorted in alphabetical order.
This is then used in the core template for the main entities menu.

Closes: #860
