Align pad URL with pad title

Rename the paramether in the route fron `id` to `name` to have
friendly urls. Use the name in the route to call `getObjectNames` which
allow us to get the id. The result need an ugly parsing to get the id,
due to the format of the response. See:
SwellRT#1 (comment)

Closes SwellRT#1.
