Allow to create maps with groups of map items

This patch lets a user create an external qml file, and put multiple
map items inside a parent MapItemGroup{}, and add that element to a Map
item.
QDeclarativeGeoMap gets also two associated methods: addMapItemGroup and
removeMapItemGroup to deal with item groups at runtime.
Additionally, clearMapItems now clears also added item groups.
