v0.1.3

The ContextMenu lived in its own popup visual tree, so the menu items'
RelativeSource={RelativeSource AncestorType=Window} couldn't find the
Window and the bindings silently failed - none of Edit / Copy URL /
Toggle / Delete actually fired their commands.

Standard WPF workaround: park MainViewModel on each DataGridRow's Tag
(still in the Window's visual tree, so the row Setter binding resolves)
and reach it from the menu items via PlacementTarget.Tag. The toggle
command parameter likewise comes from PlacementTarget.DataContext (the
EndpointConfig the row represents).
