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:
  Move QListModelInterface into util.
  Ensure ParticleMotionGravity always pulls in the right direction.
  Remove version ifdefs from Particles; only 4.7 is supported.
  Update docs for the runtime.orientation values
  Revert to Portrait/Landscape terminology for Orientation enum, with
  Add more Q_AUTOTEST_EXPORTs
  Improve input panel handling in declarative demos and examples
  Always integer align anchor center points
  Add header and footer to GridView
