Title: Map visualization

- upgrade some gems
- add profile env to trace performance issues
- add `/geo_data/tile/:zoom/:x/:y` and `/maps/:id/tile/:zoom/:x/:y` to get data that intersects a given tile
- add some scopes to geo_data:
- deselect: selects all columns except the listed as argument
- with_geojson: gets the geometry as geojson directly from PostGIS as field_geometry
- tile: gets the entries that intersects the given tile
- as_geojson: converts to feature collection
- implement the map visualization of geo data collections
- some fixes
