Merge branch '4.7' of scm.dev.nokia.troll.no:qt/qt-qml into 4.7-integration

* '4.7' of scm.dev.nokia.troll.no:qt/qt-qml:
  Cleanup minehunt example
  Keep track of the item count to avoid calling model->count() during batched changes
  Allow iteration over the Item.children property
  Add QListModelInterface::modelReset() signal and emit this in
  Compile
  Allow MouseArea.Drag.target to be reset.
  Document MouseEvent.accepted.
  Initialize drag movement correctly if drag.target is set after mouse move.
  Expand test.
  Honor the startDragThreshold in MouseArea drag.
  Don't crash if a target isn't specified for AnchorChanges.
  Optimization: Only allocate QScriptValue if we need too
  Crash: Assign context in CreateSimpleObject too
  Optimization: Minor object allocation speedup
  Optimization: Improve allocation strategy for QDeclarativeDeclarativeData
