Add extra "Malfunction" and "Off" states to Custom models

[doctormysterio12]

Describe the feature request

Within the custom models yml, add a "Malfunction" state, and an "off" state to the models.

Where, if present in the yml file, change the "solid" model to an alternative one depending on the state. The malfunction one, I'm imagining red windows, and one with unlit windows/lamp (personally my models have emissive textures, so being able to toggle them off with the power state would be a nice aesthetic addition.

Describe alternatives you've considered

None - I've suggested making it an optional state so it isn't required by default

In addition to this, consoles and time rotors could also be given this treatment

Have a "Cloister" variant for when the bell is on, automatically or by manual activation
and an "Off" state, that triggers with the power status.

This gives the option of using different colourings (IE, the "off state" texture can have a more washed out or grey-ish tone, while the on textures can use emissive textures to simulate the console/rotor being lit up
