allow attribute to set class of navigation buttons about angular-swiper

[brh55]

Sounds like an interesting idea, but shouldn't this be managed through css. External stylesheets are more performance effective then inline styles.

"swiper-button-white" is an exisitng css class in the swiper.css https://github.com/nolimits4web/Swiper/blob/master/dist/css/swiper.css.

+1 for this, mostly because I tried to specify a custom (existing element) using the override-parameters attribute like this:

<ks-swiper-container class="my-slider" pagination-is-active="true" show-nav-buttons="true" override-parameters="{'nextButton': 'my-slider__button--next', 'prevButton': 'my-slider__button--prev'}">
override-parameters="{'nextButton': 'my-slider__button--next', 'prevButton': 'my-slider__button--prev'}"

... Slides ...

</ks-swiper-container>

However this didn't work, it seems if you try and override the next and prev Button selectors the next and previous buttons no longer work at all.

If we could specify a custom class via an attribute we wouldn't need to use override-parameters to specify a custom element (maybe this is just hacking around the actual issue though...)
