Romanschangesgraphfacet

Hi Roman,

I think I made a few improvements to the facets although there are still issues with the "show more" eventually showing the wrong facets. I also added back in the tabs widget. Mostly I changed a lot of css; I want to split our big less file into a file for each widget and a utility file to keep things cleaner and easier to merge. I will do that next.

Thanks,
Alex
