keyPrefix should not be inherited by child components

[bodograumann]

When I set the keyPrefix option for a component and include a different component inside, the keyPrefix of that child component will also be set to the value I choose for the parent component. I think that should not be the case.

import Child from 'Child.js'
export default {
	components: { Child },
	i18nOptions: { keyPrefix: "view.home" } },
	template: `<section><h1>{{ $t("title") }}</h1><Child /></section`
}

Child could be used in multiple places and every time it will have a different prefix set.

I don’t think this is a good approach, because it makes the translations really hard to control.

If you really want to support it, I would suggest allowing a function for the keyPrefix option, which takes the parent prefix and returns the childs’ prefix.

In any case, please default to having no prefix, if the keyPrefix option is not given in a component.

I see the problem is also there for all other i18nOptions. Maybe there should be a new boolean option passDown, which defines whether the options will be inherited by the children of the current component.
