[js,refactor,#9][s]: remove header_content and footer_content config …

[refactor,#9][s]: switch to explicit inclusion of facetview.css (do n…

[#9,refactor][s]: much improved css and html layout for facetview.

Demo now looks quite nice.
agree to switch to classes from ids (if not done already). multiple facetviews in a page would be nice.
