Migrate all SignalR 1.x Persistent Connections to SignalR 2.x Hubs.
Abstracts ScheduledTaskStatus with core interface and adds a Mock for
optional status reporting. Noticeboards rewritten (with new theme) to be
more resilient and accurate.
Thread can be blocked until a task completes (or a timeout period
elapses). Used to wait up to 3 seconds before redirecting to the
TaskStatus when downloading the Plugin Catalogue.
