Permalink functionality (viewer)

[holiman]

Right now, when we load a testsuite, the suite get's "permalinked" by adding it to the location via history api. A better solution would be to have a "permalink" button, which would,

• put the testsuite into the url
• put any datatable filters into the url,
• put datatable sort-column/order into the url,

Loading page would then apply those parameters. It would be easy to show someone a specific result. Current viewer is here: https://github.com/holiman/testreport_template

This is improved in #348. The datatable filters etc. are not tracked, but basic navigation and linking works.

Anything beyond the changes in #348 will be a lot of work and will mess up the app code a lot. I think it would be good to split up the 'tabs' in the UI into individual HTML pages with exactly one purpose per page. It would simplify the app, but I don't want to spend more time on it right now.

Linking to tests is now possible. Closing this now because I think it's good enough.

The situation of wanting to share a specific view of the tests table with search+sort order is pretty rare, and I think it'd be kind of confusing to have a button that creates the link.
