mapwidget.qml: use a seprate animation for zooming out

The animation sequence when deselecting a zoomed in map location, should
be:
- zoom out completely
- pan to center

To achieve that a new animation object is created - "mapAnimationZoomOut"
The previous zoom in animation is renamed to "mapAnimationZoomIn".

The map functions centerOnMapLocation() and deselectMapLocation()
now call the helper functions animateMapZoomIn() and animateMapZoomOut().
