Proper fix for hiding social controls on mobile since Facebook is predictably obnoxious against a website's own CSS
Merge branch 'redesign-2014'

* redesign-2014:
  Fixes for layout changes on IE8 and IE9 	IE8 will now have a fixed minimum size essentially disabling responsiveness, as elements of the media queries aren't being applied even after shims 	IE9 will only display the logo at full width, which would normally cause the retina image to produce a double height navbar, however this situation is rare enough to be acceptable
  On IE10 and modern browsers logo can now be any size, with other navbar items auto-centering vertically. IE9 and 8 will snap these items to the top.
  Further fixes for additional content loading - a section is now no longer duplicated on the first section
  Fixed bug causing first infinite scroll block to skip a post
  Initial redesign work
