Bug: Group can be dragged even when container is locked

[jshannon-tml]

When I add the locked prop to the Svelvet container the Group can still be dragger.

To reproduce:

1. Create a Svelvet container, add nodes, add a group with some more nodes.
2. Add locked prop to container

Behavior: Hovering over the nodes shows the "no" cursor, and I cannot drag them. This includes nodes inside of the container. However, hovering over the Group, the cursor doesn't change and if I click-and-drag then the group (and its nodes) is moved.

Expectation: Shouldn't be able to move the Group.

I think that, since Groups can be quite large and take up a lot of the container, then they shouldn't have the same behavior as the node by preventing any dragging at all. Instead I think that the dragging should be allowed but should be used for panning instead. But that'd be more consistent with empty space than with nodes. So... hard to say.

We'll have this fixed in the next release. I think your behavior suggestion is a good one.
