client: add simple identify top area box * Add Identify.vue as a top area box that display the currently identified features in a short text-only way. This can be styled further, also the box is not yet resized dynamically. Put in to subdir layers because it is closest to Layers.vue, which was used as a template. * Introduce a new mapstore/identifiedFeatures state.
