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.
