Beginning of scorched earth UX improvements:

 * reduced layout.hogan.js to minimum required code (I think)
 * backpack.hogan.js (landing page) is just two columns
 * reduced style.css to rules relevant to layout

Closes #338
Removed inline style from landing page.
Duplicate two-column page for badge-details.hogan.js and
new group-details.hogan.js.
Closes #339 and #341.
