Brought back updater, but as a part of main Nootka executable. No more plugins - all that code deleted. TdialogLoaderObject handles background check invoked by main or visible check from GlobalPage.qml. Still QWidget dialog with changes. But using QVersionNumber to determine also when current version is newer than online one - testing/devel, then don't show the dialog.
