Merge lp://qastaging/~uriboni/unity-2d/launcher-autoscroll into lp://qastaging/unity-2d/3.0

* First few pixels at the top are not triggering the autoscroll.
* Autoscrolling is active even though there is not enough content to fill the ListView (for example if you have around 5-8 applications in a medium resolution monitor, the trash will not be at the bottom though if you stick the mouse cursor at the bottom of the launcher, the autoscrolling is triggered).

HACK about the mouse coordinates should be FIXME.

"Implements a ListView that have two mouse sensitive areas"
should read
"ListView that has two mouse sensitive areas"

After testing I think it would be better to have 'autoScrollSize' to be itemHeight / 2 instead of itemHeight / 3

Sometimes the following WARNING is issued in the console:

AutoScrollingListView.qml:105 Insufficient Arguments

While the workaround for the QML bug is essentially fine, it would have been simpler to write using property binding.

We do not have time to simplify it now, so let's keep it as is.

Why do you need an extra property 'spacingSize'? Using 'spacing' is enough.

Quoting my previous comment here. You will notice that not only have I replaced the 'have' with 'has' but also I removed the 'Implements a'. It's a new class, we *know* it implements something.

Fixed the last remarks and made sure the autoscroll happens only when it needs to.
Also have a look at the padding stuff in commit 394, which to me seems a quite clean way of doing it, but comments always welcome.

Good to go!
