Fix: Move Line Up/Down collapses inline editor when moving past the start/end
Enabling moving last line up
Fixing the last line move up
Save & restore scroll pos & cursor/selection of working set files across
sessions, and of ALL files within a single session.

Simplify how DocumentManager saves working set state via a new
"beforeAppClose event". There's one ugly bit, a hack in EditorManager.
_restoreEditorViewState() to get around some CM API fragility.

Also save & restore scroll pos more precisely in Quick Open when user
closes it via Esc. Remove some vestiges of the very early, incomplete &
disabled code that dynamically previewed documents as you type. Plus small
cleanup in ModalBar for clarity.

splits the unit tests into unit and integration (the split is primarily around

tests remaining as unit tests that we may still want to categorize as
integration (nativefilesystem, for example)
