Fixes for Breadcrumbs components

The continuation of #1273

#1273 (comment) here is my fixes for it
[fixed] Breadcrumb and BreadcrumbItem components (the second commit in this PR)

Looking into it more rigorously:
active property is not needed if stated functionality is implemented

An active class is added to a BreadcrumbItem if there's no href property for it.

Autosetting navItem property onto Breadcrumb children - also is copy/past leftovers.

Both id and linkId have to be string or number types instead just string (to comply with other components).

Notice

This implementation (of BreadcrumbItem) has the same weak spots as some other components have too.

• className applies only onto wrapper component
• only limited set of properties, in this case: href, target title it is possible to set for inner anchor element.
• It is not possible to set custom style or className properties to inner a or span elements.

etc.

It looks now as:

I really don't like implicitly inferring active for whichever component lacks an href. What if some breadcrumb items just don't have links? I'd be much happier if active were explicit.

[AlexKVal]

np. I'll rewrite it tomorrow.

I've rewritten it to implicitly inferring active because that was in documentation 😄
I'll fix and docs of course.

[AlexKVal]

Done.

Now it looks like:
