Schema v0.11.0-beta release

What's Changed

A. Theme-specific changes

1. Base
   • Add new land_cover feature type which is useful for generating natural-looking backgrounds for vectored map tiles.
   • Update OSM SQL to allow sport=* tags for land features.
   • Tweaks to classes and subtypes, mainly new additions.
2. Buildings
   • Promote building class to subtype and introduce new class property that is subordinate to subtype.
   • Update roof_direction validation rules to include 0 degrees so that perfectly north-facing buildings are valid.
3. Transportation:
   • Add vehicle as a supported travel mode. This had already been present in the data releases, but was missing in the schema.
   • Add is_covered flag for road segment features.

B. Pan-schema changes

• Update the BCP-47 language tag regular expression to be sufficiently permissive. (First step in our process of eliminating all language tag validation issues between the schema and data.)

C. Documentation changes

• Add additional detail to reference docs for divisions theme, particularly division and division_area.
• Enable search within reference docs.
• Add link to engineering blog.

D. Other changes

• Fix bug where special characters broke test script error matching.
