This PR adds the ability to subscribe to messages over a websocket.
To prevent polling data, the server can now push messages through the websocket, so the client can instantly update when new data is available.
The change is backwards compatible, still serving the status updates over the socket. If the client is providing the authentication token, it is auto-subscried to the legacy status message.
If the client is using the new authentication message, it needs to subscribe to get the status updates (and any other services it needs).
The event system has been extended to support new, and more accurate, events. This is the first step towards removing the general status update and the long-poll mechanism.
This also re-introduces the blocking marker, so the client can know if the operation is halted due to too many pending transfers.
Some endpoints have been moved to service implementations, to allow serving the exact same data from both endpoints and websocket.
This PR also updates the way the progress is handled, so that all transfers are returned to the client, and the transfer speeds for each transfer is calculated based on a small sample buffer, so the values are more accurate even if the program is paused during transfers.
This removes the WorkerThread class and many of the complications around it.
Instead of having a generic worker, there is now the `QueueRunnerService` which takes on all the resposibilities for handling queued tasks.
This is one step towards removing `FIXMEGlobal`

This fixes a case where the update checker keeps an old reference to the previous updated version, despite running a newer version.
It also removes some use of `Assembly.GetExecutingAssembly().GetName().Version` with the information from `UpdaterManager.SelfVersion.Version` as that should follow the update info.
