Improved the layout and messaging and user-friendliness of the create/edit a dataverse workflow, by moving the dataverse description and network homepage description to be next to another, which required moving all the network hmpg desc code from the EditHomePanelsPage to the EditSitePage. Improved the label of "Dataverse Homepage Description" to avoid confusion with the network version. Also improved layout/messaging of the AddSiteSuccessPage, to be a little clearer about what to do next. [ref 2792]
