Bug #6722, Add UI config option to always use mouse position as zoom focus on scroll

Browse source 
This means that mouse zoom scrolling behaviour is consistent on the ruler
canvas area and track canvas area.

The config option defaults to true so this means the behaviour of Mixbus will
be unchanged but in Ardour the ruler area will now follow the option so by
default will use the mouse position as zoom focus when zooming rather than the
zoom focus setting.
