Update Pagination component

[iPzard]

Add next and back buttons, using the default chevron icons (manually add the svg/react files to the component library, do not add the entire default icon library as a dependant).

Including an variant='alt-icon' options for props to use the rounded chevrons as alt icons for next and back buttons.

It should also be updated to elegantly display more than 10 pages of results. Currently, it will display a pagination option for all of them, which can seem excessive if there are 20 or 30 pages of results.

Also.. update item and itemMap references to link and linkMap (see pic).
