Avoids problems when e.g. running 'make clean' - this one tries
to delete all files named core.

Use explicit DEFINE to enable additional API in node instances for testing,
not QT_BUILD_INTERNAL.

Patch by Marco Bubke.

Task-Number: BAUHAUS-449

This patch is eliminating the switch from the state the base state and back if a property is changed.
 For that it is updating the internal caching values in QDeclarativeState.

Reviewed-by: Thomas Hartmann

All files have been renamed from Qml to QDeclarative.
Registration of types is now done in an initializer method.
QmlView/QDeclarativeView doesn't have an execute method any more.
QDeclarativeMetaObject became private API.
QmlMetaProperty / QDeclarativeProperty has now different API.

Task-number: BAUHAUS-259

This adds a new "Design" mode that can be used to manipulate qml files
in a visual way. It will only get build if you have the declarativeui
module in Qt.

This is a squashed import from the Bauhaus project. Share & enjoy :)
