fiddling with redirections and some placements:
  'white kitty head' in nav goes to portfolio if logged in
  '[user]' in nav goes to portfolio
  added 'cog' to nav when logged in to go to user settings
  shifted the 'log in' and 'sign up' buttons a bit to the right in nav
  fixed broken drop down nav in about
  landing redirects to portfolio if logged in
  landing main text is now centered
  registration button now on left in registration landing
