Warning: changing database schema

FYI: today I’ve been working on simplifying the database schema and, with ShrimpTest in beta, I am not going to build a migration script. If you would like to upgrade to this upcoming (later today, and beyond) version of ShrimpTest, I would recommend you simply clear out all your experiment data (deleting the experiments, or just clearing the wp_shrimptest_* tables).

More information on what exactly I’ve changed will come after I finalize everything and commit these changes.
