TD: fix undo/redo for dimension objects

Browse Source 
* do not emit dragFinished() signal inside mousePressEvent as nothing has been done. This avoids to create an empty transaction and doesn't touch the document
* inside mouseReleaseEvent() check if the mouse has been moved and only if yes emit the signal
* improve error handling in mouseDoubleClickEvent
* in mouseDoubleClickEvent start to edit the view provider
