New Speckle Server admin features

Hey Server Admin @Community

As detailed in our recent blog post, we have added two new server admin panels.

One for sending out server invites to a list of addresses and one for managing the users of the server.

The panels have a basic set of functionalities, which we are planning to expand.

Let us know what features / use-cases you would like to see for server administration.

The new goodies are available with our @latest release tags, but they will make their way into a proper release soon.
