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:
  Rename example component file for clarity
  Improve docs on QML Animation page and associated elements
  Fix warning from whining complier.
  Re-enable script program caching on Symbian (used to be disabled due to crash problems that no longer occur).
  Increase drag distance on Symbian to improve finger usability on capacitive screens
  Increase maximum heap size of QML Viewer
  Add missing test file.
  Make sure onFocusChanged is correctly emitted for items in a FocusScope.
