Prevent saving Recent Files and LastTargetDir if history is disabled

Summary:
Disabling history in Settings → Configure → Advanced → History
does not prevent showing and populating File → Open Recent.
The last target directory for Copy/Move/Link To dialog does not check
for history option too.
This patch only saves/restores file history if the option is enabled
and hides the menu entry if disabled.

• Enable/disable history option
