User menu draft re: #16, PR #21 and #31

This is a next step for the User menu first described in #16, then PR #21 and now #31.

It uses Foundation’s dropdown menu component. Please look at comments in the code for additional details.

I am expecting to back off from coding as we move along but this was a great help in my learning process with using Foundation. I would summarize those learnings this way:

• Foundation has fabulous documentation - well worth browsing to get acquainted and then returning to when there is a specific need/use.
• Foundation works fine in our site.
• An easy way to test various Foundation components in your local dev instance is to use footer.php and insert the demo code just below the end of the php-based comment and before the other html.

Thanks for the research! I'm going to close this in favor of #36.
