Should have been done earlier. 2.1.80 was burned in the pre-2.1.0->2.0.1
days, and we'd like to have odd subminor for 'working' and even subminor
numbers for pure cherry-picking release branches anyway.

Also introduce a indirection, modes have now types, edit and debug have
the same type, and editors do have a prefered type of modes instead of a
prefered mode.

That fixes the bug that if the prefered qml editing mode was set to
design, then in switching between qml editors would
- in Edit Mode: stay in edit mode
- in Debug Mode: switch to debug mode

... on canceling.

Do an initial connection check on the host
(once per host). Add utility function to
NetworkProtocol, displaying connection check
message box.
Move the 'Paste' handling into the PasteView
dialog, such that the checking happens there
and the dialog stays open if something fails.

asynchronousShutdownFinished signal. During that time an event loop
is running.

A mostly mechanical change.
