Small fixes to Browser.qml

- focus highlight should not be shown if user presses any physical key, only when up, down, left and right arrow keys are pressed
- hybrid devices (touch + four-way rocker) showed two highlight at the same time after using rocker and pressing the screen with finger
- touch highlight had gradient, focus highlight one didn't
- the width of the focus highlight didn't update when listview changed size (for example after orientation change)
