Add new method to BindingRegisty for simple class naming

[wolfieboy09]

Description

Lot's of bindings are mostly classes, and most times it's just the class name, and so this can simplify it a bit for adding a binding

Example Script

public void registerBindings(BindingRegistry bindings) {
    bindings.add(SomeClassName.class); // This get's registered into kjs as "SomeClassName"
}

I considered doing something like this in the past, but this kind of introduces an antipattern of not naming your bindings properly at all, like for example, a lot of classes will have a "RecipeOutput" class and all of those bindings would then clash
