Feature: Node's search from blender

[tonis2]

The page for searching/uploading node trees at here https://node-runner.thiering.org/ is great.
But maybe it would be possible to have a node-tree widget right in the blender.

Just my theoretical first plan.

1. The addon can use node-runner page api, to search/upload node trees directly inside blender.
2. The addon should have a simple UI widget, where user can search node configs, see their descriptions, maybe rating ?
3. User could log-in from blender addon settings.
4. User can upload configs to node-runner api, directly from blender.

Thank you for the issue! I really like the idea! I've been working on that for a while now and it's almost finished!
