Themes

Applying some themes to the website looks a little strange because I'm used to default panopoly now.

Trying a dark theme here, lighter easier to read on FerretBiology...we'll see as things progress.

Had to change how many menu items we had, too many caused some line breaks...would be more suited for single article pages but not stuff with side menus. So limited back to 4-6 and used subcategories.
