More map improvements

• Improved marker & marker shadow (after consulting stuff with our graphics designer)
• Allow embedding map collection campaign logo
• Improve map back & forward navigation (migrate from hashbangs to query param), allow anchoring to page category list or map by using URL hashbang
• Add Mapbox tiles provider - in disabled state as we're still waiting for MapProxy
