Filter Sliders

Filter slider almost done. Main page almost done. This commit contains a
bunch of unnecesary js and css files for the sliders, ill delete most
when I figure out which ones are needed.
Update filter layout, Move js to js file.

Changed the layout of the filter panel. Range sliders now open beside
the main panel instead of below. Added slide animation. Moved the
index.html javascript to it's own file.
Merge branch 'Lee'
