Missing Clara2E comment labels

It's been brought to my attention that we forgot to add the Clara2E to the various comment labels in nickel.yaml and libnickel.so.1.0.0.yaml.

I've just updated all the nickel.yaml occurrences to add Clara2E to wherever ClaraHD currently appears. However, I'm not 100% sure whether the same logic applies to occurrences in libnickel.so.1.0.0.yaml.

I think it's only Custom font sizes and the 3 keyboard patches which are affected.
