Get rid of QGCView, QGCViewPanel and FactPanel. All messages and dialogs are now handled in the root window.

On desktop (Ethernet connection), the ground unit pushes UDP directly, which makes the use of an actual "Link" not possible. Instead, I've moved all of Taisync support to a "manager" owned by QGCToolbox.
Added a Taisync settings with some basics already wired and running.
