Allow logic processor's look up and @id process terrain

Describe the content or mechanics you are proposing.

Add options like floor, ore to lookup, and let the sensor @id return the corresponding numeric id.

Describe how you think this content will improve the game. If you're proposing new content, mention how it may add more gameplay options or how it will fill a new niche.

Storing terrain in memory is currently a cumbersome process that requires players to design their own coding system. If this feature is added, it will make it easier for the world processor to handle this issue.
