Feature clean up whitespace and encoding

This is a pure clean-up pull request. When you look at the first commit without whitespace changes, it [disappears](https://github.com/ospalh/Anki-Android/commit/18b6f71252951280132cb0154274d17aebb83ff6?w=1).
The second corrects the last messed up  “Sv�ｽ�ｽrd” i could find.
