[enhancement request] extract g:paginate to this plugin as f:paginate

The reason being pagination is something that is frequently used, and it can potentially be customized in terms of theming.

As of now, I'm doing a custom taglib to do my pagination style using Bootstrap 4 as shown here. https://gist.github.com/kevintanhongann/0d912951c66e1240a8859fcea4fdab0e

Start by locating the existing g:paginate tag and compare it with the custom taglib and Bootstrap 4 example linked in the issue. Done means the plugin provides an f:paginate tag whose pagination output can be themed or customized as requested.
