Fixing setting of @sequence and @sequence.theme
Improved display of HAS sequence navigation menu

For [#51593657]: now that the menu shows sequence activities, we see the current activity as a blue "button" and its pages in blue; all the activity blocks have a pseudo drop-shadow. Also content from the page beneath (e.g. the Facebook like icon) is hidden by the menu. Still missing: the arrow glyphs next to the activities and the "MENU" text; the top bump-out indicator; a gradient on the current-activity background to give it button-like texture.

Remove the extra padding for the fixed navigation from HAS styles
Gradient on the active activity "button"

Puts the gradient on the active activity link in the activity/sequence navigation menu for [#51593657].

Some progress on sequence menu borders

Fixes the border color; a note on a possible approach to do the indicator angle on the top border. https://www.pivotaltracker.com/story/show/51593657 [#51593657]
use more general selector for image questions

This makes them work for 'image' interactives as well

only select first element in interactive div

This means for 'image' type interactive the caption
and credits won't be snapshotted. Currently Shutterbug
doesn't handle multiple element selectors very well.
It will set the size of each element to be the size 
of the first element. This creates lots of whitespace.

Adds the arrow to the top of the navigation menu

This is the last big piece for [#51593657]: the top border includes a sort of arrow up to the menu button to visually indicate the link between itself and the control which opened it. (Added two empty divs to the HTML which got styled to represent the "arrow".)

Adds up and down arrow glyphs to HAS themes

This adds the down white arrow to the "MENU" trigger, and the up grey arrows to the activities inside the menu. There are notes on the last glyph, the white down arrow next to the active activity, which is a little trickier so far.

Ensure answers to multiple-choice selects are saved

…and restored when returning to the page.
Check Answer works as expected for select menus

[#51944625] On-change event is set on menus to activate the 'Check Answer' button. AnswerChecker script is updated to get values from the menu and submit those for validation.

Use font-awesome glyphs for arrows instead of images

Much more elegant solution to the up-down glyphs in [#51593657] - better-looking glyphs and easier to match color and position.

Properly set width of embeddable carousels

For [#53567925] - the width was set incorrectly because the code wasn't correctly picking up which layout was being used.

Smarter height setting for embeddable carousels

This ought to finish the fix for [#53567925]; it's a bit smarter about setting the height of the containers, so we can hope it will fix our problem child. I'm going to deploy it to check.
