QListWidget itemActivated does not follow S60 conventions

The problem is that on touch phones Symbian lists work like this:

• If you do a single click on the current item, it is activated
• If you do a single click on non the current item, the current item is changed but not activated

Qt should work like this

This is in 4.6 beta1 did not try in 4.6 RC1 because it makes our app unusable due to other bugs.
