Plugin for sumneko/Lua VSCode extension.

For now this plugin just replaces "#include" with "require()",
it does not behave exactly same as in game,
and will be improved in future releases,
but works fine with relative paths.

Add next settings to ".luarc.json" in project's root folder and replace paths.
