#90074: Added event fired by PersistenceGeo Context when a layer is removed from the server.
Removed english title from the dialog shown when persistence geo parse makes an operation against the server.
Added message box telling the user a layer's deletion from the server was succesful. That is now possible due to a "layerremoved" event having being added to PersistenceGeo Context idue #90074.
#90074: Added listener to PersistenceGeo Context's "layerremoved" event so we can delete a layer's metadata in geonetwork.
#90074: We remove metadata associated to a publication request when it gets rejected.
