Last URL is incorrect for collections

When fetching collections, the client will dive deeper to get more details
on each entity. The "From $url" was showing incorrectly, including the last
of these deeper queries (for just one entity), rather than the actual
collection query.
Customize display for new events view

This tailors the output for `razor events` and `razor events $id`.
