Initial work to make liniting easier. This includes: - Rename http_request.js to library_godot_http_request.js. - Rename externs.js to engine.externs.js. - New library_godot_runtime.js (GodotRuntime) wraps around emscripten functions. - Refactor of XMLHttpRequest handler in engine/preloader.js. - Few fixes to bugs spotted by early stage linting.
