Lua filter: allow natural access to meta elements
Meta elements that are treated as lua tables (i.e. MetaList, MetaInlines, MetaBlocks, and MetaMap), are no longer wrapped in an additional table but simply marked via a metatable. This allows treating those meta values just like normal tables, while still making empty elements of those values distinguishable.
