Add instagram sharer. Along for the ride is a new config value for where to present popovers from. This is only interesting on the iPad as the DIC is presented as a popover. Images are scaled to 612 on the longest side, non square images that are not 612x612 are letterboxed with white.
Added the scope param to make sure our access token has correct access privileges. Also force a relogin for currently authenticated users.
Re-added debugging wrapper.
Moved scope to a define, removed template leftover comments, removed unused defines.
