ManhattanStyle: Remove a hack for QComboBox wheel scrolling

Browse Source 
Use Utils::setWheelScrollingWithoutFocusBlocked() explicitly
when a QComboBox is placed inside a scroll area.

The Utils::setWheelScrollingWithoutFocusBlocked() is more
general and may be applied to other widgets, like QSpinBox.

This patch brings back the wheel scrolling without a modifier key
for combo boxes placed in dialogs.

Keep the unconditional scroll wheel behavior when ctrl (meta on mac)
modifier is pressed.
