This PR is a **documentation change only**. It documents the fact that `name:xx` values are present in the tiles and documents that `name_de` and `name_en` will be removed in a future release in favor of `name:de` and `name:en` respectively.
Improved update performance of water_name layer
- Implemented diff updates for update_water_lakeline.sql and update_water_point.sql
- Unified update_water_lakeline.sql and update_water_point.sql to update_water_name.sql
- Refactored IDs to be unique in water_name_marine.osm_ids
- Restricted updates to INSERT and UPDATE operations during water_name_marine.refresh
- Added analyze statements before update queries during water_name_marine.refresh
* At zooms 9-13, water labels will now be rendered for water features that are at least 0.25 tiles in size. This means that water features that are the same size as a 128x128 pixel square will get a point label.
* Labels for large water features are now shown at the lowest zoom at which it's appropriate to show a label.
* Bay and strait names (`natural=bay` and `natural=strait`) are included.
* Large seas modeled as areas (e.g. Caspian Sea) render as `class=sea` rather than `class=lake`
