updated UI

things changed:
- removed tables from layout
- updated jquery UI (+jquery) while making a fitting theme
- two layouts: mobile (viewport width < 960px) and large screen
- resized the map to 300px with scale2, so it should look good on a mobile screen, and I'd say it's ok on a pc too (albeit smaller)
- OpenSans (regular and light) as a base font (the whole glyphset)
