Don't scroll to top after toggeling a track

[auric]

On the "Tracks" screen, there is this behaviour when you have a lot of tracks (on a Desire HD it is clear when you have more than 8, preferably more than 16 tracks)
- Scroll down to the bottom
- Select/deselect the last track
- The list scrolls back to the top.

This behaviour is annoying when you want to select/deselect multiple tracks in the middle of the list, since you have to search for the correct position :-)
