Refactored UI to use fragments. Deletebutton doesn't work yet.
Created detailsroom as dialogFragment instead of pure fragment. Cleanup needed, but hey - it works :)
Refactored: Instead of using pure Fragment on the details, it is now a DialogFragment. By now it works, but we need to populate it with data from the db.
Enabled the WifiSensor in MainActivity.java to get the wifi-sensor to work. The app crashes without this.
