Lua scripting

Rationale
Templates and ParserFunctions were introduced to allow end users of MediaWiki to build, effectively turning wikitext into a limited programming language.

However, complex templates have caused performance issues and bottlenecks.

This project aims to make it possible for MediaWiki end-users to use a proper scripting language that will be more powerful and efficient than ad-hoc ParserFunctions-based logic.
