🐜Improve Docs & FeathersVuexPaginate

Many GitHub issues were closed related to the documentation.

The FeathersVuexPaginate component was upgraded to automatically paginate to the last page when on a higher page and the total pageCount drops below the currentPage (as happens when you filter/search the results). For example, if you're looking at page 40 and you perform a search which limits the total results to three pages, the page will automatically switch to page 3.
