Feature Request

Like #4058, paginator() helper needs to be customizable and needs to have customizable classes.

We need options like prevClass, nextClass, spaceClass, allClass, currentClass, etc.

A lot of CSS framework like Bulma are working 100% with classes, so not being able to set a class on the generated tags make the use of the helper impossible.
For example with bulma a <h1> won't be stylized without a class, it needs class="title is-1", the same apply for all elements.

I will have a look at the required pagination structure for:

• Bulma: https://bulma.io/documentation/components/pagination/
• Bootstrap: https://getbootstrap.com/docs/4.3/components/pagination/
• Spectre.css: https://picturepan2.github.io/spectre/components/pagination.html
