Working version with team names and external css stylesheet

 - moved if/else statement under the index page route
   (was in the wrong route)
 - changed if/else statement to use the array of hashes in the each loop
   (was using the array of hashes per team, which was incorrect)
 - added a "/" to the beginning of the stylesheets URL, so now the
   team/team_name webpages now have the stylesheet applied
