Add sorting. Fix preferences.

Added sorting for the record. Now the preference actually works and the record is reordered on the fly.

TODO: On-the-fly reordering without entering preferences (should be really easy to get).
Separate strings.xml

Separated strings.xml into different files for better tracking of the strings and translation.
Add demodata.

Added string with demo data.
Fixed rotation.

Rotation is now fixed, shows the proper information in the proper places and keeps the state.
