Promote some geo feature collection items
In order to attract more reader attention and prevent users leaving right away, support promoting serveral collection items which will be shown right on top hopefully above the fold. The section title is optional and customizable.
Some other minor stuff:
- Enabled smooth scrolling on the website. While it has lot of advantages, it also has some drawbacks so I'm leaving this open for further discussion.
- Clean up & fix geo feature detail to only list parts with usable content.
- Unify & clean up context for geo feature collection map.
