Add a button in Corona Converter to unplug Falloff maps in Fresnel mode from the Base IOR slot

After converting some objects from Vray into Corona, some materials end up having the Falloff map in Fresnel mode in the Base IOR slot.

Normally I unplug all these manually after the Corona error signs pop-ups, but l think it'd be handy to have a button in the Corona Converter that allows us to unplug all of them at once. Unless there's already a work around for this?

Thanks in advance for considering this idea :) And thanks for all your work in Corona ❤️
