Add FavoriteArtists midlet

This will be useful to develop and later test our implementation of the Gesture API and the Frame Animator API.
The Makefile specifies UTF-8 encoding to the javac command, but these appear to be in ISO-8859, which causes javac to complain:

```
midlets/favouriteartists/ActionCommand.java:2: warning: unmappable character for encoding UTF-8
 * Copyright � 2013 Nokia Corporation. All rights reserved.
```

So we should convert them to UTF-8 (or compile them with the proper encoding).
