client: add measurement and improve identify * Only display features that have an Id in the identify box, because during the drawmode, after the first click, there is an additional feature that has no Id. Probably this is the point. * Add setting an Id to the feature that is drawn, which makes it show up in the identify box. * Add code to add the length of the drawn line to the store and a rounded value to the feature property. This creates a simple measurement tool, if the feature box is shown.
