* [v3 linux/systray] dbus generation * [v3 linux] systemtray dbus implementation * [v3] add 'id' for MenuSeparator This is needed in order to have a unique value for all menuItem(s) such that the Linux implementation doesn't have to generate new identifiers. Allowing the reuse keeps a 1-1 mapping in place without any extra effort. * [v3 example/systray] add radio group to example * [v3 linux] stub out ExportStatusNotifierItem callbacks Can only seem to get the `SecondaryActivate` to fire when doing a 3-finger click! I was expecting a right-click interaction to trigger it.
