Update multi-machines to display running mode in GUI (#2755)

* Framework for mode text in gui

* Add getMachineModeName to all multimachines

* Changed lang file for MFE because "Electromagnetic Polarizer" and "Electromagnetic Separator" are too long and make the GUI look bad

* Removed leftover code

* Removed more leftover code... oops

* Moved logic to base class and made mode switch chat message localizable

* Merge caused spotless to fail, I guess

* Reverted logic from parent class

* ahhhh spotless
