Ess 0.5.1

Data only — 1_Ess.lua is unchanged apart from the version string. If you only install the framework
there is nothing here for you. It exists because api/natives.json gained a field that downstream tooling
needs.

Fixed

• published_global on natives.json namespaces. 0.5.0 correctly reclassified Hud.*, Pda.*,
  Cheat, MapLabel, MessageBox, Minimap, ObjectiveTray and SubtitleBuffer as game_script —
  they are resident Lua with readable source, not C++ natives. But game_script conflates two things.
  Most resident scripts are reached by import()ing the module that owns them; these are assigned straight
  into _G (_G.Hud = HudInterface in mrxguiinterface.lua), so they exist from load with nothing to
  import, and import("Hud") is meaningless because no module has that name.

  Consumers had no way to tell the two apart. The web IDE maps game_script to "modules" and its linter
  tells you to import one, so after 0.5.0 it began advising import("Cheat") for a global that has always
  simply been there. The classification was right; the data model was too coarse to express it. 38
  namespaces now carry the flag, and the kinds block documents what it means.
