Allow (or force) Editable to be False when using functions

[KathleenDollard]

Normally if the ClassName() function is used, the contents should not be editable. I don't find a way in CSStudio to set this to false - it could just always be false perhaps for the functions.

Thanks Kathleen, yes I agree that there should be a way to set it to false. I'll implement one :-)
