Remove "n" list field setting, decrease OC-LuaJ size.

Setting "n" inside a numbered list was only fully supported up until Lua 5.0,
and was fully removed by Lua 5.2 (which is the lowest version we support).
To improve performance and memory usage a little, remove setting it across
the OpenComputers Lua world (including in our fork of LuaJ).

In addition, more unused LuaJ code was removed, saving about ~100-130KB after
JAR compression.
