To keep the Jasmine runner happy, we need to have rack-environmental ignore its pages, and I had to bend rack-environmental a bit to make that possible.
Runs can remember their sequences
Specs for sequence-aware activities
Activities are sequence-aware

If an activity is launched from a Sequence page, the sequence id is part of the URL. If the sequence ID is part of the URL, the sequence is stored as part of the Run data, and whenever the user comes back to that run, the activity sets the appropriate @activity variable for use by whatever needs it (e.g. theming).

Assets for HAS module themes, with backgrounds

This splits HAS into five themes, which share a common CSS file (has-styles.scss) but also have custom files which pull in different background images (and, eventually, different header graphics). This is most of [#53912853]
