Kinetic scrolling can be disabled via the API.

Default is on except for the N900.

To deactivate kinetic scrolling manually, do:
- when using Marble as a library:
  MarbleWidget *marbleWidget = ...
  marbleWidget->inputHandler()->setKineticScrollingEnabled(false);
- when using Marble (KDE version):
  $EDITOR ~/.kde/share/config/marblerc
  Add a new line 'kineticScrolling=false' (no quotes)
- when using Marble (Qt version, also Nokia N900/N950/N9):
  $EDITOR ~/.config/kde.org/"Marble Desktop Globe.conf"
  Scroll down to the [MarbleWidget] section
  Edit 'kineticScrolling=true' to 'kineticScrolling=false' (no quotes)

No user interface for it yet, but adding one in the desktop version
might be useful (in the Navigation settings).
