5.3.0

This minor release for dask-labextension includes a few new features and bugfixes.

1. The extension now uses the new Dask logo and branding. For more discussion, see this issue.
2. There is a new configuration option browserDashboardCheck which can force the extension to check for a Dask dashboard using the frontend browser session (rather than a request made on the server side). This can be useful in cases where a browser cookie is needed to authenticate to the dashboard. Thanks to new contributor @viniciusdc for implementing the feature!
3. There is an error message which suggests the user might have a misconfigured/not-installed serverextension if it is not found. This was a little overeager, resulting in some false positives. In this release it should be a little slower to show the message. (cf #237)
