Selected node label hard to read

[maxkfranz]

Describe the bug
A clear and concise description of what the bug is.

It's hard to read the selected node label when it's crowded.

To Reproduce
Steps to reproduce the behavior:

1. Expand a bubble.
2. Click a node in the bubble.
3. Can you read its label? Usually, I can't unless I drag the node out.

Expected behavior
A clear and concise description of what you expected to happen.

• The selected node should be on top.
• The selected node should be black and its label outline should be black.
• When expanding a bubble, it should apply a grid layout to the children so that they don't overlap. We can fade out the other nodes, outside of the bubble, kind of like the Wine and Cheese app.

We discussed using a grid layout when the cluster is expanded. We could also fade the rest of the network when a cluster is selected.

Indeed, the label is more legible when the selected node is on top and the label outline has the same dark color as the node border:

AFTER:

Of course, this is only true if the adjacent/overlapping nodes are not selected as well.
