Improve homepage
(deleted) requested to merge (removed):master into master
I removed the navbar from the homepage again because it looked very ugly in the current form. Instead I added the user dropdown to the place where login and sign up are shown and removed these buttons if the user is already logged in. Additionally I removed the if condition for showing the home button in the navbar because this button makes sense when logged out,too.
