WIP.

A commit just to save my work.
Almost working version of the test page.

This commit breaks the main page because it deletes some overly zealous
CSS properties.

Still todo: export the tests results, use the currently mounted agents,
include version information.
Use currently mounted agents for tests.
Restore centering cells on the project page.
Remove useless log entry.
Add export as text option.
Remove now useless files.
