Implement machine linking (#1784)
* Implement machine linking * Cleanup and rename Signals * Implement signal button * Add machine linking signal mapping * Fix signallink command help * Add localization to signal linking and allow infinite range * Add feedback for when a transmitter is not connected to any receivers Refactor PopupMessage to use the entity extension Refactor dependencies to not have to disable warnings
