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`
In some cases the stored database state would be misinterpreted causing abnormal wait periods that crashes the program on startup.
This change converts all time compares to UTC asn the database value was already UTC.
It also adds a clamping function to prevent crashes on extreme values (using 24h pause instead of crash).
Re-implemented everything using ASP.NET.
Changed some requests to use JSON instead of FORM data.
Some work towards deleting the FIXMEGlobal instance.
Auth is missing, XSRF does not work correctly.
