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: (32 commits)
  Correctly support translation in QDeclarativePixmapCache
  Improve warning for non-Item delegates.
  Correctly support translation in QDeclarativeCompiler
  Small calculator fix.
  Improve declarative calculator example.
  Update examples autotest to use the runtime directly
  Support valuetypes as method return values
  Compile without Qt3 support.
  Doc
  Simplify dynamic resource loading to avoid cluttering Text API.
  Add Component.onDestruction attached property
  Use qmlInfo for image loading errors, not qWarning().
  Visual test updates.
  Rename section so that it's not linked to by references to "JavaScript"
  Doc improvements
  Comments
  Remove unused parameter
  Correctly resolve, and load, IMG tags in Text element.
  Rename "sql" test so autotester doesn't get confused.
  Should work now, don't skip.
