  Add a dir() function to improve API discoverability

The purpose is to simply list everything that's available in a given module or object.

Currently, it only works for tables. The plan is to extend it to userdata objects if and when it is approved.

  Lua: Refactor the AI module to be dir()-friendly

This places all read-only functions straight into the AI table, which means it sticks when stdlib.lua nulls out the old move map API.

The AI table then implements the __dir metamethod to add the mutating functions in if read_only is false.

This also adds a __dir metamethod for the aspects table which gets the list of aspects directly from the engine.
