Filament autoloading improved and minor tweaks

Filament autoloading now acts like normal loading (Error message pops out if nozzle too cold, Printer asks if should extrude more when done loading)

Autoloading now unable to turn on when filament sensor is turned off or not responding

Color not right changed to color not correct to avoid slight confusion
