Fixes some things with the DA and R&D machines in general

Created by: 9600bauds

Fixes #4475 (closed) Fixes Protolathe/Circuit Imprinter material storage screens not working anymore after #4565 Fixes an issue where all R&D machines were returning null when their panel was screwdrivered open Fixes runtime when deconstructing DA which was causing a second machine frame to be spawned and the original DA never being deleted (and I assume, blueprinter and reverse engine, didn't test it on those) For whatever reason, machines giving the "needs to be connected to an R&D console" error were then returning 0, which was bad Fixes #4561 (closed), this was actually an issue with screwdrivered open DAs still allowing you to jam an item inside, DAs with items inside can still be linked properly. Shouldn't happen anymore, slap me if it does.
