Category Clean Up

As always, we are constantly trying to make the site easier to navigate.  The most recent changes should help that a little.  First off, some of the category names have been changed to try to make them more descriptive.  With that, all posts have been sorted so that they are only in one category.  Mostly that keeps the layout pretty, but it should also help keep navigation tight.  The second modification made for navigation is at the bottom of the page.  Previously there were only ‘Next’ and ‘Previous’ options, meaning that to find a specific post readers may have had to navigate numerous pages using those tabs.  This has been changed to page numbers  to help jump through posts a little more quickly.
