bitbake: toasterui: URL refactoring

This is a URL refactoring needed to remove the inadvertent
usage of server-side user session in a REST-style API.
We move the parameters that were stored in the user session
to the URL, making navigation more robust.

This refactoring allows a clean (no 500 HTTP return codes) crawl
of the website following inside links.
