Fix #3568
Created by: dylanstrategie
attack_robot did not include AIs, and since the silicon clause was removed from attack_hand to effectively allow MoMMIs to interact with the tray, and attack_AI returns attack_hand by defauly, it led to !!FUN!!
- Fix AIs ripping out plants and generally fucking with hydroponics trays
This file as a whole might need some tidying up at some point, but important fixes first
