This patch implements the command and dispatchers for
synchronising the selection between Qt Creator and the qml2puppet.
Qt5InformationNodeInstanceServer::changeSelection() is called whenever the selection
is changed in Qt Creator.
Qt5InformationNodeInstanceServer::changeSelection() allows to change the
selection from the qml2puppet.
